We are not called to give our opinions; we are called to obey. If you are not humble, then you cannot obey, because you are operating under earthly, demonic, wisdom. Every aspect of life is addressed by the Word of God, and it all comes down to this:  humble yourself and do it God’s way. That is how a Christian acts toward himself and others. We speak words of edification, not words of death, and we require those around us to do the same.
