You are still doing it: deciding for God what and how He will or will not do things according your humanly reasoned understanding of scripture mixed with the things of man. Consider again this which I am certain you have heard before:
"For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD.
For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts." Isaiah 55:8-9
They could not get there in the OT. So one reason Jesus was sent to make the impossible possible for each of us. But.. He did not send Jesus and the Holy Ghost so we could use our brains to figure it out. That failed in the OT but now it is possible for whosoever will [not many are really willing] , but only by the power of God working in individual being prepared to perfectly into the Body of Christ. Don't presume to say what God can or cannot do; or what God will or will not do!
Why did David dance before the Lord with all of his might when his own wife was embarrassed and ashamed of his seemingly very worldly display? But David in spite of his failures was called the apple of His eye and a man after God's own heart. He did not do that by following the impossible to keep laws [in which he failed miserably], but by always admitting his own frailty and always being ready to pay the price of death which law would have required. For murder or adultery the law prescribed death, but God forgave David because of David's heart which God was watching all of the time. He wasn't watching His adultery and murder, saying, Oh now I am going to get him. No, He was watching the heart of man, like we are men, who was willing to die because he loved God and he knew he had been disobedient. Are we willing to do as much? We cannot judge others, because we cannot see their hearts. How clearly can we see even our own hearts?
Perhaps many people in these "movements" you condemn so self-righteously actually received something good, that is something from the only One who is good because of their hearts. Did you not see one of them? No, so then condemn the whole thing because it looks awful bad to you!
You said that God is not the author of confusion and so it is, but everyone of us who is still double minded has confusion mixed with the good things of God. [Only those who have already overcome the world as Jesus did, are not double-minded serving God on the one hand and sinning on the other when we quench the Spirit in us.] That is what in the end of the matter could cause us to be spit out of His mouth. I include myself too, because I know that I have not yet overcome all that stands between me and God, but the end is not yet. I am hopeful, not because I have been given definite confirmation of my salvation, but because I strive to always love God even in the worst of times and I know that He is fair and loving and merciful. That is not a guarantee, but a hope!
