Is there anywhere I can find a list of everything in the Bible that is a sin?

Answer:

Such a list cannot exist. God told us everything we need for life and godliness (II Peter 1:2-4). His word equips us for every good work (II Timothy 3:16-17). However, while sin is discussed, it cannot be written out in full. The reason is that men are constantly inventing new ways to sin. "Truly, this only I have found: That God made man upright, but they have sought out many schemes" (Ecclesiastes 7:29). This is why the road to heaven is described as being narrow but the road to hell is wide (Matthew 7:13-14). There is only one way to heaven, but anything that is not that one way leads to hell.
