When God speaks a word to you and it's a promise, it is as good as done!  However, when that promise seems to take much longer than what we were anticipating, we start to figure out the things that we have to do to help God out. God will keep us on a "Need to Know" basis so we don't try to mastermind how it is that we should make that promise come into existence.  Keep these words in mind "God does not need your help!"
