Everyone has sinned—done things wrong—from “big” things like murder to “small” things like envy or gossip. Because we have all disobeyed God in one way or another, we are all deserving of the judgment for this, which is death. Jesus Christ came to take our judgment upon Himself, and though He was innocent, He willingly died on the cross for us,. When He did this, He took all your sin upon Himself.
The Bible says that Jesus “was wounded for our transgressions…and by His stripes we are healed” (Isaiah 53:5). When you put your trust in Jesus Christ as your Lord and Savior, you are set free from all judgment for your sins and from the punishment of death. Everything you have done wrong in the past is forgotten by God and He makes you into a new person: “Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!” (2 Corinthians 5:17)
“As far as the east is from the west, so far has He removed our transgressions from us” (Psalm 103:12).
“If you confess with your mouth that Jesus is Lord and believe in your heart that God has raised Him from the dead, you will be saved” (Romans 10:9).
“If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness” (1 John 1:9).
“God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.” (2 Corinthians 5:21)
