My guess is that everyone of us has at one time or another been let down by someone who didn’t keep their word. It’s also very likely that we too, have been the someone who has let others down. It can be for a variety of reasons. But Scripture is very clear that God is always faithful. He will and does always keep His word. Period. He never falters. He never changes His mind. It’s never half done. He never forgets. It may not be in the time we expect it, but He never fails. We can trust Him. If we ever doubt that He will keep His word, we lack faith. We must have faith in His faithfulness.
