Religious people (in the bad sense of the word) focus on so called 'big' sins (homosexuality, murder etc...). But God sees all sin as sin. Lying is just as wrong in the eyes of God as homosexuality. Course language is just as punishable as murder. This is made clear in James 2:10, "For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it." To receive the forgiveness that we all need, He doesn't ask us to do things, He just asks us to change the way we think, turn away from the wrong things we do and believe in His Son. By believing I mean that we accept that He was perfect, that He was the Son of God, that He took the punishment for out sins on the cross, and that He was resurrected. If we ask for forgiveness and believe in Jesus, that, in turn, changes us. Because of His sacrificial death (taking the punishment of our sins), if we believe in Him, all our sins are forgiven and we get to spend eternity with Him. If we believe in Jesus, God promises us that He will never punish us for our sins, because Jesus has already taken that punishment for us. In my mind, that's a good deal. I don't know about you, but I've done and said things in my past that I'm ashamed of (and I still blow it now and again).
