Have you given up on trusting God for something that seems humanly impossible, but you have His word on it? Have you quit believing because you don't have any evidence that it has never happened before; because you think it is taking too long, because you don't see any use in waiting, or because God is unable to do it?
"God is not human, that he should lie, not a human being that he should change his mind. Does he speak and not act? Does he promise and not fulfill?" (Numbers 23:19). When God commands a blessing, there is no one anywhere that can prevent it. If you have dared to take God at His word, do not stop believing now. You may be closer to a breakthrough than you think or know. Keep believing just because it is God who said so.
Blessings!
