Words dominate us. Whether positive or negative, words control our lives. This is why we must be extremely careful to guard our tongues, especially when bad thoughts come to mind. Thoughts that are never spoken or acted upon will die unborn. It’s not until we give a thought voice and act on it that Satan has an open door into our lives.
But God has to be given permission to work in this earth realm on behalf of man. You are in control! So if man has control, who no longer has it? God. When God gave Adam dominion, that meant God no longer had dominion. So God cannot do anything in this earth unless we let Him. And the way we let Him or give Him permission is through prayer.
