Shame on you, pulling one verse out of context does not make your point. You will find my response on the other thread.
1 Cor 2:14-16
14 But a natural man does not accept the things of the Spirit of God; for they are foolishness to him, and he cannot understand them, because they are spiritually appraised. 15 But he who is spiritual appraises all things, yet he himself is appraised by no man. 16 For who has known the mind of the Lord, that he should instruct Him? But we have the mind of Christ.
NAS
If a man or women claims to be a Christian and lives an openly proud gay life you can and should gently show them the truth. However if that person's ignores the truth you are to let them go their way since God will judge their lives, not you.
Here is what Jesus taught about confronting a brother engaged in sin:
Matt 18:15-20
15 "And if your brother sins, go and reprove him in private; if he listens to you, you have won your brother. 16 "But if he does not listen to you, take one or two more with you, so that by the mouth of two or three witnesses every fact may be confirmed. 17 "And if he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax-gatherer. 18 "Truly I say to you, whatever you shall bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven. 19 "Again I say to you, that if two of you agree on earth about anything that they may ask, it shall be done for them by My Father who is in heaven. 20 "For where two or three have gathered together in My name, there I am in their midst." NAS
You start with a private conversation, then confront him with 2 or 3, and then the before the congregation, not on something as impersonal as the Internet and not to the exclusion of being gentle. If such a person ignores church discipline he is to be ostracized and the issue is closed. To continue to harp on the issue is being judgmental and ignores Christ’s teaching.
