How do you become a Christian?
First of all, you don’t become a Christian by joining a church, adopting a creed, or by believing in God.
Jesus
John 3:16 tells us: “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.” Jesus is the most important figure in all of human history. He is God in flesh (John 1:1,14; Col. 2:9), physically risen from the dead (John 2:19-21), Lord (Luke 24:34), and Savior (Acts 5:30-32). He came to die for sinners (Rom. 5:8) and to deliver people from the righteous wrath of God upon us.
Are you a sinner?
I ask you, are you a sinner? Have you ever lied, stolen, lusted, coveted, or been angry with someone unjustly? If so, then you have broken the Law of God. God has said “You shall not steal; You shall not lie; You shall have no other gods before Me; You shall not murder, etc.,” (Exodus 20). He has given the standard of righteousness and if you have broken any of God’s commandments then you have fallen short of that standard and are under the inevitable judgment of God. When you die you will face Him and on the Day of Judgment He will punish all sinners.
Jesus is the One you need. Him alone. Not your works (Rom. 3:10-12; Isaiah 64:6). Not your sincerity. Not your goodness. You have nothing to offer God except your sinfulness. It is only by the love and grace of God found in Jesus and His sacrifice that you can be delivered from the righteous wrath of God upon all who have broken His law.
The Bible says that all have sinned and fallen short of the glory of God (Rom. 3:23). That means that your sins have caused a separation between you and God (Isaiah 59:2) and the result is death (Rom. 6:23) and wrath (Eph. 2:3). The only way to be saved from the wrath of God, is by faith in Christ (Eph. 2:8-9; Rom. 5:1). You must trust in what Jesus did on the cross to forgive you of your sins and not trust anything else, not even your own sincerity. That’s right, sincerity isn’t good enough. Why? Because sincerity is an appeal to God based on the goodness of your own heart. If you’re appealing to God based on the goodness of your own heart, then you’re being prideful. Sorry, salvation is either based on Christ alone, or it is not. This is why it is Jesus and only Jesus who can turn away the righteous judgment of God upon the sinner.
The Gospel
The gospel is that Jesus died for sinners on the cross, was buried, and rose from the dead (1 Cor. 15:1-4). His death was a sacrifice that turns away the wrath of God (1 John 2:2). This is the only way to be saved.
Jesus is the one who died for the sins of the world (1 John 2:2). He is the only way to the God the Father (John 14:6). He alone reveals God (Matt. 11:27). He has all authority in heaven and earth (Matt. 28:18). It is only through Him that you can be saved from God’s wrath (Eph. 2:3). He can forgive you of your sin (Luke 5:20; Matt. 9:2). He can remove the guilt that is upon your soul. Jesus can set you free from the bondage of sin that blinds your eyes, weakens your soul, and brings you to despair. He can do this because He bore sin in His body on the cross (1 Peter. 2:24) that those who trust in Him would be saved.
If you are not a Christian, and want to be delivered from the righteous judgment of God upon you due to your sin against Him, then come to the One who died for the sins of the world. Come to the One who died for sinners (Matt. 11:28). Turn from your sins. Believe and trust in Jesus. Receive Jesus, who is God in flesh, who died and rose from the dead (1 Cor. 15:1-4) as your Lord and Savior. Ask Jesus to forgive you of your sins. Receive him (John 1:12). Only He can wash you clean from your sins and only Jesus can deliver you from the righteous judgment of a holy and infinite God. Pray to Jesus. Seek Him. Ask Him to save you.
He will.
Here is a sample prayer you can offer to Jesus. It does not have to be exact, but you will get the idea.
Lord Jesus, I know that I have sinned against you. I know that I am not perfect and that I cannot please you through my own efforts. I know that I deserve to be judged according to my sins. And, I know that I have nothing to offer you.
Lord Jesus, I ask you to forgive me of my sins. Please cleanse me and make me right before you. I trust in what you have done on the cross. I do not rely on myself but only on you and I receive you as Lord of my life and as savior of my soul. Lord Jesus, save me. I look to you alone.
