I'm allowed to discern between spirits. God will judge me accordingly, I am prepared for that.I am glad to hear something positive from you. Be more careful about speaking the negative... or your own sake.
Remember that the negative words you speak about anyone else's testimony without a clear direction from God to open your mouth your words may be the basis for your own negative judgment. We are judged based on our own ways without regard to whether the other guy's words spoken are right or not. God does always know right or wrong of every issue, and He also knows when we do not. Right or wrong on an issue, belief or doctrine God is looking to see how merciful and charitable we are... especially toward those with whom we disagree.
But I will rebuke someone when, in my opinion, they're talking nonsense, and I expect, and hope, that others will do the same to me.
I am not fearful amadeus, of the repercussions of being wrong, not in the context that I'm speaking. God knows that I'm defending him when I'm being 'negative'. That's always been my position, don't mock God.
