Who Is Jesus, Really? What the Bible Says About His Identity and Why It Matters

There is perhaps no more important question in all of history than this: Who is Jesus? The answer shapes everything, from how we understand love and obedience, to how we find victory over sin, to what happens when we die. First John chapter 5 gives us a clear and powerful picture of Jesus's identity and what it means for our lives today.

The attack on who Jesus is did not begin in modern times. It goes all the way back to the Garden of Eden. When the serpent approached Eve in Genesis 3, he was not simply questioning a rule. He was attacking the very character of God.

By saying "you surely will not die," the serpent was really saying that God was an oppressor who did not love His creation. That distrust of who God is led to disobedience, and that disobedience broke the relationship between God and man. Sin has separated us from God ever since.

The same kind of attack on Jesus's identity was happening in the early church through a false teaching called Gnosticism. A teacher named Cerinthus was spreading the idea that Jesus was merely a human man who temporarily received a divine "Christ" power at His baptism, which then left Him before the crucifixion. In other words, God did not truly become human, and the Christ did not truly die.

It was largely in response to these errors that the Apostle John wrote both his Gospel and his letters. The stakes were high then, and they remain high today.

First John 5:1 says, "Whoever believes that Jesus is the Christ is born of God, and whoever loves the Father loves the child born of Him."

God is not simply a being who chooses to love. He is love by nature because He has always existed as a relationship within Himself: Father, Son, and Holy Spirit. Before He created anything, there was always the Father loving the Son, the Son loving the Father, and the Spirit in that same eternal bond.

This is why we can say, without qualification, that God is love. Other conceptions of God cannot make that claim, because a God who is absolutely singular had no one to love before creation. But the God of the Bible has always had someone to love within Himself.
We are created in His image, which means we are made for loving community. This is why God created Adam and then said it was not good for Him to be alone. To be fully in the image of God, we need relationship with others.

The family, the church, and our love for one another all reflect the very nature of God Himself.

Have you ever wondered why God gives the commands He gives? It is not arbitrary. God's commands are not a list of rules He invented. They are a revelation of His own nature and character.

Consider the Ten Commandments. "You shall have no other gods before Me" reflects the fact that God has no gods above Him. "Do not commit adultery" reflects the fact that God does not violate His covenants. "Do not bear false witness" reflects the fact that God does not lie. Each commandment is a window into who God is.

This means that sin is not simply breaking a rule. Sin is an attack on God's person. It is open rebellion against who He is. And obedience is not just following instructions. Obedience is an acknowledgment of who He is, a way of honoring and loving Him with our lives.
First John 5:2-3 says, "By this we know that we love the children of God, when we love God and observe His commandments. For this is the love of God, that we keep His commandments; and His commandments are not burdensome."

To love God is to obey Him. To pursue being like Him is to love those around us. Jesus made this clear in Matthew 22 when He said the greatest commandment is to love God with everything you have, and the second is to love your neighbor as yourself. These two commands work together. You cannot truly love others the way God calls you to without first pursuing God with your whole heart.

First John 5:4-5 says, "For whatever is born of God overcomes the world; and this is the victory that has overcome the world, our faith. Who is the one who overcomes the world, but he who believes that Jesus is the Son of God?"

Overcoming the world does not mean being perfectly obedient. John knew that Christians would fail and sin. He already wrote in 1 John 2:2, "If anyone sins, we have an Advocate with the Father, Jesus Christ the righteous; and He Himself is the propitiation for our sins; and not for ours only, but also for those of the whole world."

Our victory is not found in our own perfection. It is found in His. Jesus lived the sinless life we could not live. He died the death we deserved. He rose again, defeating sin and death on our behalf. Those who believe in Him have overcome, not because of what they have done, but because of what He has done. Sin will not destroy you, because the One who has destroyed sin lives within you.

First John 5:6-12 makes clear that Jesus was not divine only at His baptism or only before the cross. He was God from the very moment of His conception. Matthew records the angel's words to Joseph: "Behold, the virgin shall be with child and shall bear a Son, and they shall call His name Immanuel, which translated means, 'God with us.'" He was not called Immanuel at His baptism. He was called Immanuel because that is who He is from the beginning.

John 1:1 and 14 confirm this: "In the beginning was the Word, and the Word was with God, and the Word was God... And the Word became flesh, and dwelt among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth."

John points to three witnesses that confirm who Jesus is: His baptism, where the Father declared "This is My beloved Son"; His blood, the perfect sacrifice that cleanses us from sin; and the Holy Spirit, who testifies about Jesus and dwells within believers.

The conclusion is this: "He who has the Son has the life; he who does not have the Son of God does not have the life." Eternal life is not a box to check or a ritual to perform. It is a relationship with Jesus Himself. As Jesus prayed in John 17, "This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent." The word "know" here is intimate and relational, not merely intellectual.

There is widespread misunderstanding about who Jesus is, what He did, and why He did it. This misunderstanding exists outside the church, but it also exists inside it. Many people who have trusted Christ cannot explain even basic truths about Him.

The Great Commission calls us to go and make disciples, baptizing them and teaching them to obey everything Jesus commanded. That requires us to know what He commanded, not just know about it. We are ambassadors for Christ, and that means being able to clearly and lovingly explain who He is and why it matters.

Romans 10:9-10 says, "If you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; for with the heart a person believes, resulting in righteousness, and with the mouth He confesses, resulting in salvation."

Confessing Jesus as Lord is not fire insurance. It is a submission decision. It is acknowledging that He is the Lord of the universe, that He deserves your allegiance, and that when you and He disagree, He is not the one who is wrong. Love is not a feeling.
It is an action.

To love God is to submit to Him as Lord and to walk in obedience, not perfectly, but persistently.

This week, take one concrete step to deepen your knowledge of who Jesus actually is. That might mean reading through the Gospel of John, having a conversation with someone about your faith, or simply sitting with one of the Ten Commandments and asking what it reveals about God's character and how you are living in light of it.

Ask yourself these questions as you go:

• Do I actually know who Jesus is, or do I only know about Him? Is my faith based on a relationship or just a decision I made at some point in the past?
• When I look at my daily obedience, does it reflect someone who loves God, or someone who is just trying to avoid consequences?
• Am I able to explain to someone else who Jesus is and why His identity matters? If not, what is one step I can take this week to grow in that?
• Is there an area of my life where I am not making Jesus Lord? What would it look like to surrender that to Him this week?

He who has the Son has life. That is not just a theological statement. It is an invitation to know Him more deeply every single day.
