I think the major point to be made is that God knows that all of us are sinners. Sin is beyond our will. The term "we're only human" comes into play here. I've been saying this, but I don't think it's catching on. Jesus came here and died for us because we're all dirty sinners. Every day. Technically, to make a comparison, if you're married and you even think about somebody else in a lustful way, it's a sin. I'd be so bold as to say that a gay guy thinks about being gay as much as a straight guy thinks about casual sex. If we ask for forgiveness and let him into our lives by believing in Jesus, that's what Christianity is all about.
