In John 8.21, Jesus warned the unbelievers, "I am going away. You will look for me but you will die in your sins." It struck horror in me to hear the part "you will die in your sins." It means dying with sins still unforgiven ~ a state I never want to be caught in! Jesus is here to forgive our sins ~ not taking advantage of this is to commit suicide (pardon my language, but it's the truth). Repentance easily takes care of our sins, unless you think you are just too almighty to bow to the Lord.
