One of the reasons that so many in the church are having trouble with gay marriage, and the idea of a gay Christian, is because they have set their hearts on the idolatry of free will. Since they are the ones who made a decision for Christ, on their own terms, then how can they say that the gay man or woman who comes to Christ and yet remains gay despite this being contrary to the gospel, cannot come to the gospel on their own terms as well. In other words, the believer in free will is dictating the terms of the gospel. So too is the man or women trapped in the abominable sin of homosexuality. They are doing the same thing as those who declare it is their free will that led them to a decision in Christ.
Thankfully, there are those of us who clearly see that both positions are flawed. We don’t get to set the terms of our salvation. If we come to Christ, we must do so on His terms, not ours. That means we must be born again, made new creations in Christ, and have union with Him. This being the case, there is no room for holding onto any other identity. If a gay man or woman trusts in Christ, then they must die to the identity and that sin, just as the rest of us must die to our own identities and our sin. We are no longer of the flesh, but are called to walk in the Spirit and live in light of the new creations that we are in Christ.
All this to say, the free-will approach is now reaping what they have sown and this is why men like Andy Stanley in Atlanta are openly accepting gay marriage. The true believer, the new creation in Christ, sees this for what it is, a false conversion of someone who is no more a Christian than a Muslim.
