If God is going to do something we don't have to make it happen with our strength. If God has promised you something, you don't have to make it happen. Below is quote from Beth Moore that says this even better:
"when God seems to be prompting something out of the ordinary, we don't have to manipulate things to make it happen and cause people to accept it."
God is never late. If things haven't happened, if you haven't been healed, if life just isn't coming together as you think it should, then God is asking you to wait and believe, wait and believe, wait and believe. Oswald Chambers wrote something about God's silence being an indication that He's trusting you will hold onto His promises.
That's not always what we want to hear but He gives grace to us for the wait. Use it.
