Christianity: The Only Thing That Makes Sense

Christianity: The Only Thing That Makes Sense

Nick Esch 8/7/2019


I have a great desire for people to come to know, love, trust, and follow Jesus… For their good and His glory I want to see as many people as possible become Christians. And that’s the heart behind this post. In what follows I’ve sought to look at some of the core aspects of Christianity through the lenses of basic logic and reason. My hope is to show that not only is Christianity logical, it’s the only thing that truly makes sense.

Arrogance In Unbelief

Before I came to know Christ I was an atheist… Or at least I thought I was. If I’m honest, I was a very inconsistent atheist. Though I claimed to not believe in God, because of the many horrible things that had happened in my life—such as my father’s suicide when I was 17 years old—often my posture was, there is no God… and I hate Him… I was bitter. And I was also arrogant. I thought I had everything figured out, and that Christianity (and all other religions) didn’t make sense. To me religion was just a way to get people to behave. I thought you had to check your brain at the door of religion, take a leap of blind faith, and then you could feel all warm and fuzzy and pride yourself on being better behaved than everyone else… But, I was a fool.

By God’s grace I heard the gospel and came to realize that Christianity is the only thing that does make sense. When God opened my eyes and opened my heart to the gospel, I didn’t have to check my brain at the door, but on the contrary, I began to truly use it like never before. I found that faith was not a blind leap but something supported by logic and reason. I found that atheism as well as every religion except Christianity, was illogical… I found that in my unbelief I was checking my brain at the door and simply believing what the world had been telling me to believe.

The Faulty Logic Of The World

In a nutshell, the world says that everything came from nothing. That once upon a time there was nothing, and then suddenly a big explosion happened that created the universe as we know it, which then gave way to evolution, and now here we are millions of years later. But there’s a major problem with that theory… Nothing doesn’t explode! Existence doesn’t come from non-existence. Something doesn’t come from nothing. Logically speaking, in order for anything to exist something must’ve always existed. The idea that nothing plus nothing equals everything and everyone is illogical… It doesn’t make any sense.

Logic, Existence, And Intelligent Design

If we believe that anything exists, that we exist, then logically we must conclude that there has to be something or someone that has eternally existed from which all things derive their being—their very existence. Now some argue that space or some sort of universe has always existed, and that that’s what gave way to the big bang. But, even if that was true that still begs the question, what created the universe that created our universe? What created space and such that gave way to the big bang? And does it really make sense to believe that our perfectly ordered world is some sort of cosmic accident? The fact that we have intelligence and the fact that our bodies, this planet, the solar system, and the like are structured in just such a way that life is not only possible, but flourishes, points to intelligent design, not a cosmic accident.

Logically speaking, in order for anything or anyone to exist, something or someone must have already existed… Because something doesn’t come from nothing. And if we take and honest look at ourselves and the world around us, it makes far more sense to believe we came from someone, not something… What the universe is by its very nature, and who we are by our very nature points to intelligent design, not a cosmic accident… That said, it makes far more sense to believe that all of existence derives its existence from an ever-existing being, not merely some thing or substance, but a person. And this is essentially what most major religions argue: that the some-One who has always existed, and the One from Whom all things get their existence is God.

Logic And God

The Bible says that God Himself is the ever-existing One. In His Word He calls Himself, “I Am!” Meaning He is and has always been… Which is what we see in His Word. The very first words of the Bible tell us that in the beginning, or even before the beginning was God… And then He created everything and everyone… Everything and everyone derives existence from the ever-existing One. But as I said, at some level this is what every major religion claims, so how do we know the Bible is right? How do we know the God of the Bible is really God—the ever-existing One?

The All-Sufficient One True God Is Triune

While on the one hand I could point to the historical accuracy of the Bible, the eye witness testimonies of the resurrected Christ, and the faithful witness and testimony of those who laid down their lives for Christ to show the truthfulness and reliability of the Bible; on the other hand I can use logic and reason to show that the Bible is true and that the God of the Bible is the one true God. Only the God of the Bible, only in Christianity is God triune. The Christian God—the one true God—is the trinity: three persons, one God… God the Father, God the Son, and God the Holy Spirit.

So, now that we’ve established that the existence of anything mandates the eternal existence of Someone, an intelligent Someone—God—because something doesn’t come from nothing, let me show you why this God must be the God of the Bible. In order for God to be God, the ever-existing One, He must be all-powerful, all-sufficient, and perfectly good in every way. These things are simply a part of the godness of God. He is the God from Whom all things flow; so if everything gets its very existence from God, then everyone in all their strength and all their power, and everything in all its strength and all its power, and whatever good there may be in things or people all comes from God… they derive their strength, power, and goodness from God, who then must be all-powerful, all-sufficient, and perfectly good. Whatever power or goodness we see in creation is merely a shadow or a mere taste of the power and goodness of the Creator… He is the source for all these things… If God is God, and He truly is the ever-existing One, then He must be all-powerful, all-sufficient, and perfectly good.

Well, if God is all-sufficient then why would He create? If He needs no one, then why create anyone? Some religions say God created because He was lonely… Other religions say He created for entertainment or so that He would have slaves to serve Him or please Him… But all of this implies that God is not really sufficient in and of Himself… it implies that He needs something or someone. And that implies that God is not God… It implies that He’s needy or a tyrant, not an all-powerful, all-sufficient, perfectly good God. Only in the God of the Bible do we find a logical reason for God to create.

Only In The Trinity Do We Find A God Who Is Love

Because the God of the Bible is triune we can see that He is love, because He has always been loving, because He has always had Someone to love. Within the Trinity there is perfect communion, perfect relationship, and thus perfect love. The Father has eternally loved the Son (Jesus), the Son has eternally loved the Father, the Spirit has eternally loved the Father and the Son, and so on… As God’s Word says, “God is love” (1 John 4:16 ESV), and this is true because God is triune. If God was a single person, like the gods of other religions, he would not be love or loving because he would not have anyone to love. He would be dependent on his creation in order to become loving, and if he’s dependent on his creation he’s not really god… But, the God of the Bible is triune and is loving, and it is His love that led Him to create. Out of an overflow of love for His Son, God created so that His creation could glorify Him, and so that His people could love Him and delight in Him. The love of the Trinity overflowed into creation so that we could enjoy and participate in the love of God as well. So, why did God create? Because He is love; because He loves His glory in His Son; and because He loves us…

Logic, Love, Justice, And The Gospel

And so that’s what God did: the glory of God and the love God so overflowed that God created. He created us—mankind—especially to glorify Him and to enjoy Him forever. But we have rebelled against Him and against the very purpose for which we were created. We have sought out our own glory, loved ourselves, and lived for ourselves above all else. And in our rebellion we have thus offended the ever-existing God—the all-sufficient, all-powerful, perfectly good, truly loving, infinitely glorious God. And because we’ve offended the infinite Being our offense is an infinite offense. Every sin we have committed, everything we’ve ever thought, said, or done that was not for the glory of God was an infinite offense against God. And because God is perfectly good He is perfectly just; and justice demands that the punishment fit the crime. So, every sin we have ever committed deserves and infinite punishment; and that’s what every sinner is condemned to: to suffer God’s eternal wrath in an eternal hell. God must punish sin because He is perfectly good.

But, because God is love, because He so delights to magnify His glory in and through the person and work of Jesus Christ, He made a way of salvation for His people. Jesus, God the Son, came to earth and became man (though staying God), and lived the perfect life for God’s glory that we have failed to live, and then He took the punishment we deserve upon Himself by having God’s eternal wrath due sinners like me and you, due His people, poured out upon Himself on the cross until it was completely satisfied. Because Jesus is Himself the ever-existing infinite God, He can take on and satisfy an infinite punishment. Because He took on flesh and was like us in every way, yet without sin, He was a suitable substitutionary sacrifice, and because He is God He was a sufficient sacrifice. Because He’s eternal He was able to take on a punishment that would take us an eternity in hell to take on in just a few hours on the cross… And then He died the death we deserve. But He did not stay dead. On the third day He rose from the grave showing that He truly is God in the flesh who has power even over death, and showing that God the Father had accepted His sacrifice, and that the sins of His people had been paid for. And His people are all who turn from their sin (rebellion), trust in, and follow Jesus…

This grand act of redemption happened because God is love; because He loves His Son, and loves to magnify and display His glory in His Son, and because He loves His people God made a way of redemption that makes much of Jesus and enables His people to make much of Jesus. As God’s Word says, “God shows his love for us in that while we were still sinners, Christ died for us” (Romans 5:8 ESV). “Christ loved us and gave himself up for us” (Ephesians 5:2 ESV). And He did all of this, “to the praise of his glorious grace, with which he has blessed us in the Beloved” (Ephesians 1:6 ESV)… So that we might be so amazed by who God is in His glory and how He’s loved us that we would so love Him and delight in Him that we could not help but praise Him for His glory—the glory that we see most evidently in the person and work of Jesus.

As God’s Word says, “for all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation by his blood, to be received by faith…” And it goes on to say that God saves His people this way, in and through Christ on the cross, “so that he might be just and the justifier of the one who has faith in Jesus” (Romans 3:23-26 ESV)… In and through the cross the glory of God, the manifestation of who God is and what He’s like, is made most evident, because there we see the justice, anger, wrath, fury, mercy, grace, and love of God most clearly. There we see that God doesn’t merely allow sin to go unpunished, but that sin will either be punished in hell, or it has already been punished on the cross in Christ.

Many think this all sounds too narrow. I’ve had people protest after I’ve shared the above things with them, saying, “It sounds like you’re saying that everyone who is not a Christian is going to hell, and that the only way to not go to hell is to turn from sin, trust in, and follow Jesus…” To which I reply, “You’re absolutely right!” On the one hand, Jesus Himself said, “I am the way, and the truth, and the life. No one comes to the Father except through me” (John 14:6 ESV). And on the other hand, if God is truly good and just Jesus must be the only way of salvation. God can’t simply forgive sin because that does away with justice. Because God is good justice must be served, and in Christ it has. Only in Christ do grace and justice, and mercy and wrath meet. Jesus is the only way of salvation or there is no way… or God isn’t good… And if God isn’t good then He isn’t God…


There’s so much more I could say here, and so many other ways I could lay out the truth of God’s Word and the gospel, but what I hope you see is that the Christian faith is logical; repenting and believing the gospel—the good news about the person and work of Jesus—is not a blind leap of faith. People act as though the theory of evolution, or that believing everything was created by chance is somehow logical and Christianity isn’t. But, I hope you can see that the Bible is logical, the gospel is logical, Christianity is logical; in fact, Christianity is the only thing that truly makes sense. So, if you haven’t already, beg God for forgiveness for your sin and to grant you grace and faith so that you would turn from your sin, trust in, and follow Jesus.

Don’t be foolish like I was… Christianity isn’t about feeling warm and fuzzy and being better behaved than everyone else; it’s about knowing Jesus, loving Jesus, living for Jesus, and delighting in Jesus. It’s about knowing the truth and truly living in light of it. However, in those things we find joy and assurance, and are enabled to live more upright and moral for the glory of God. And after all, since God is the ever-existing One, who is all-sufficient and perfectly good, it only makes sense that true satisfaction and true joy are found in Him alone—in knowing Him, loving Him, living for Him, and delighting in Him… So, if you’re not a Christian I pray you become one, and if you’re already a Christian, I pray that what I’ve laid out here would comfort you and bring you assurance, and better equip you to contend for the faith once for all delivered to the saints.
