We need to listen to our brothers and sisters in Christ who self-identify as gay–remember, temptation is not a sin. Giving in to temptation is a sin.
There is no more reason to be standoffish from someone who has been tempted with gay sexuality than there is to be standoffish with a heterosexual who has been tempted by an extramarital affair and walked away from temptation.
All sexual sin is disordered, in its own way. Saying no to it is a step toward the Saviour, no matter what that temptation was.
When we say Christ’s blood breaks the power of all sin, we have to say that with conviction. All sin!
