A pastor I sometimes like to listen to is John Piper. Here is a sound clip of him talking about whether pornography addiction is an unforgivable sin. Is Porn the Unforgivable Sin? I think it’s a pretty good clip.
It’s helpful to us as Christians who sometimes fail with crossdressing. I know that in my own experience I’ve doubted my own salvation countless times after crossdressing failures. I knew crossdressing was sinful, but knew that I’m forgiven for my sins in Jesus. And yet I failed so repeatedly in the addiction in the past, that I wondered if I was willfully sinning and actually not a true Christian, or if I was committing sin to the extent that it was unforgivable.
Pastor John reminds us that God is long-suffering and patient with us. It’s not too late. If you struggle with such a question that means you are not giving up, which means God is moving you to repentance. Repentance is the key. As long as you always have true repentance you are a child of God and enjoying God’s mercy. If you find yourself unrepentant of sin, and at peace with your sin, that is when you should wonder whether you really have a relationship with God at all, whether you’ve been transformed by the love of Christ.
But, if we are in Christ, we keep making war against our sin of crossdressing as long as it takes, no matter how long it takes!
