Trust God, for he knows what is right. (except, i have a man who thinks he deserves it, and honestly, he does not deserve it) so perhaps God will place my heart in the hands of a man who truly deserves it!
Until God opens the next door, praise him in the hallway. I think this quote is just a cliche and doesn't mean much to anyone until they find themselves in a hallway and see how difficult it can be to trust and praise God in times of waiting.
It always annoys me when people attribute quotes to the wrong sources, usually to celebrities. For instance, this quote was song by Barlow Girl, but it was originally scratched onto the wall of a Cologne Germany concentration camp.
