Most people who grew up around church can tell you something about Jesus. He was born of a virgin, lived a sinless life, died on the cross and rose again. But a quieter question sits underneath all of that: what does any of it have to do with me?
The Bible itself is shaped around that question. The Gospels tell us what Jesus did. The Epistles spend their pages explaining why it matters and how it changes us. Jesus did not simply die on a cross; He died on the cross for you.
One helpful way to see why Jesus matters is to look at three great movements in the Bible’s story: the fall, the law and the cross. The fall is the problem. The law is the opportunity. The cross is the sufficient solution.
The Fall: The Problem That Became Everyone’s Problem
In the garden, God gave Adam one command about one tree, with one warning: “in the day that you eat of it you shall surely die” (Genesis 2:17). Adam and Eve ate, their eyes were opened, and they hid from God among the trees. In that moment sin entered the world, and there was an immediate separation between God and the people He made. Read a little further and there is a second separation, between Adam and Eve themselves.
It did not stay in the garden. “Sin came into the world through one man, and death through sin, and so death spread to all men because all sinned” (Romans 5:12). The fall is the problem that became everyone’s problem.
Two kinds of sin
Romans 5 shows that there are two kinds of sin. The first is the sin we do. Everyone has done something that dishonors God, usually by the time they can say their first few words.
The second is the sin we inherit. Paul writes that death reigned “even over those whose sinning was not like the transgression of Adam” (Romans 5:14). No one else can sin the way Adam did, yet his sin has traveled through all humanity. Theologians call it the sin nature: a bend toward sin that makes us want to do what we know is wrong. That inherited nature is what actually separates us from God.
This is why the church cannot focus only on behavior. You don’t clean a fish before you bring it into the boat. God brings us in first, and then He does the cleaning.
Two kinds of death
Because there is sin, there is death, and there are two kinds of that too. Physical death comes to everyone. Spiritual death is what Paul means by being “dead in your trespasses” (Colossians 2:13). Until a person is born again through the blood of Jesus, he is spiritually dead, and spiritual death causes everything it touches to die. Every area of life is affected by it.
The Law: The Opportunity That Became a Revelation
Thousands of years after Adam, God revealed His power to Israel and to the nations through Moses, as if reintroducing Himself as the one true God: “Hear, O Israel: The LORD our God, the LORD is one” (Deuteronomy 6:4). At Mount Sinai He gave the law of Moses, with the Ten Commandments as its cornerstone. It was an opportunity: do right by this standard and be blessed; do wrong and be cursed.
There was one problem. It did not work.
We do not even have to wait for the New Testament to learn this. Joshua, who served alongside Moses as a young man and lived to be 110, spent decades watching Israel live under the law. Near the end of his life he told the people, “You are not able to serve the LORD, for he is a holy God” (Joshua 24:19).
The apostle Paul explains why. “God has done what the law, weakened by the flesh, could not do” (Romans 8:3). The law did not reduce sin; it exposed and even provoked it: “the law came in to increase the trespass” (Romans 5:20), and “the power of sin is the law” (1 Corinthians 15:56). Anyone who grew up hearing nothing but “don’t, don’t, don’t” knows how that works.
But the law did accomplish something. It became a revelation. It showed all of humanity that we are entirely unable to live up to God’s standard. “So then, the law was our guardian until Christ came, in order that we might be justified by faith” (Galatians 3:24). The law showed us we need something outside ourselves to be made right with God.
The Cross: The Sufficient Solution
That something is the cross. God forgave all our trespasses “by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross” (Colossians 2:14).
Jesus solved the fall
One man’s disobedience made many sinners. One man’s obedience makes many righteous. “But the free gift is not like the trespass” (Romans 5:15). Paul says that “much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ” (Romans 5:17). What Jesus did at the cross is more powerful and reaches farther than what Adam did in the garden.
Jesus solved the law
“There is therefore now no condemnation for those who are in Christ Jesus” (Romans 8:1). Jesus fulfilled every requirement of the law on our behalf, “in order that the righteous requirement of the law might be fulfilled in us” (Romans 8:4). That gives believers the full rights and benefits of someone who has kept the law perfectly.
Jesus solved them sufficiently
Jesus did not partly solve the problem. Hebrews 7 calls Him “the guarantor of a better covenant” (Hebrews 7:22) and says “he is able to save to the uttermost those who draw near to God through him” (Hebrews 7:25). Unlike the priests who offered sacrifices again and again, He offered Himself “once for all” (Hebrews 7:27). There is nothing left to add. When Jesus said, “It is finished” (John 19:30), He meant it.
How Does This Work in My Life?
If the work is finished, how does it become yours? “For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast” (Ephesians 2:8-9).
You do not earn it. You believe it. When you put your faith in the finished work of Jesus at Calvary, grace releases everything you need. Your belief releases His supply.
That is why Jesus matters. The fall was everyone’s problem. The law proved we could not fix it. And the cross fixed it completely. “Everyone who calls on the name of the Lord will be saved” (Romans 10:13).
