I don't believe God will ever give one man the power to sit in judgement of another, no matter how they click their heels together........not working....
No one ever said anything about judgement, you put that in, we are talking about the Holy Spirit revealing to man so they can help the sinner, such as the sin of David with Bathsheba.
Because David did that which was right in the eyes of the LORD, and turned not aside from any thing that he commanded him all the days of his life, save only in the matter of Uriah the Hittite. 1 Kg.15:5
But in the case of the wheat and the tares, it is the tares that choose a seperate path from God, and the Holy Spirit lets us discern and reveals it so we may not fall into the path they are going.
