There might not be a phrase in existence, but if not, there ought to be, and it goes like this: Without God, there is no future. This holds true for each and every one of us. Unless we have God, we have no future here on earth worth remembering, and certainly no future in the life beyond. Sadly, most of us find ourselves doing the opposite. Without Future, there is no God. We decide that if we can't have what we want, then we won't let God stay in our lives.
The irony, I think, with this sort of belief is that whether we really think God exists or no, our idea is that somehow we'll be spiting Him by rejecting him. Does God need us? No. He wants us, and loves us, and wants our devotion, but not because he needs it in any way. We, on the other hand, are very much in need of him.
There is something to be said in having a future torn away and knowing that God is still God, and that with Him, we still have a future, even though it might not look like we imagined it would. I don't think that there is any further moral or principle to this situation; but I would say that in time of our greatest need and weakness, we find that God is still there and cling ever closer to him.
