Jesus can save you, just like he saved us.
The Bible says God is holy. That means He is perfect. He has never done anything wrong, and He will never do anything wrong. Because God is Holy, God hates sin.
The Bible says man is not holy, but completely sinful. We have all sinned. We have all broken God's law.
Our sin separates us from God in this life and the next. We will spend eternity separated from God in a real place called Hell because of our sin.
But God passionately loves us. He made a way to bridge the gap between God and man through His son Jesus Christ. Jesus was born, lived a sinless life, died for out sins, and rose three days later in the flesh. Jesus alone saves.
You respond by turning from your sin to God. The Bible calls this repentance. You tell God that you believe in Jesus Christ and you are trying in Jesus to save you. By doing this, you are committing to live according to God's design and follow Christ.
