I don't agree with this at all. Matt Chandler's church in Dallas has a small group for people that struggle with same sex attraction. If you struggle with this, you are gay. I have never been tempted in the least by this, it repulses me just like it repulses every other straight person. But I think that making blanket statements like this is neither Christlike nor helpful. I think it actually just causes people to feel more hopeless. I think we need to extend grace and be very careful about commenting about things we know little or nothing about.
I was wounded in a major way by a pastor that did just that. It caused me to completely run away from the Church or anything Christian at all. It was just too painful. When you attribute people's words as an extension of God's words, it can really damage you emotionally. My struggle is with OCD. It's a very real struggle that affects every aspect of my life, and is a personal hell. For a long time, I kept this part of myself private. But as I started to open up to people I trusted, I was accepted and loved. I was on my way to accepting myself. Then I told my pastor. He knew nothing at all and don't think he had ever even heard of OCD, but he told me that it was a sin, and I needed to repent. It hurts even now, 15 years later. I'm sure his intentions were good, but he caused a lot of hurt, and it was completely wrong for him to do that.
I don't know why the Church demonizes homosexuality like it's an unredeemable sin. We go to porn conventions and tell porn stars that Jesus loves them, and some get saved. But all we ever do is judge homosexuals. I don't know about you, but I have plenty of sin, including sexual sin, in my past and present. And no doubt, my future also. Making war against sin is a daily choice, but we will always have failures. It's rumored that Rich Mullins struggled with homosexuality and I think it's been confirmed that he had major struggles with alcohol. I also think that he loved God and influenced the world with his music. Was he not a Christian because he struggled with sin? Homosexuality is a difficult issue that we need to be very careful about. If someone is gay, they are going to struggle with it for the rest of their lives, no matter their intentions. It is wrong, no doubt. We shouldn't encourage someone to just live out a gay lifestyle like it sounds like Rob Bell did. But the call to salvation goes out to all, and Jesus looked at the multitudes and was moved with compassion for them. We need to love them and offer them the Gospel. Let God deal with their homosexual issues over the course of their lives, just like he deals with our heterosexual issues and the multitude of other sins that we are each prone to in our uniqueness.
