Have you ever made a promise you couldn’t keep or has someone done that with you? It can be painful and disappointing when this happens.
God doesn’t have this problem and Maverick City Music sings about this in their song “Man of your word”. In Joshua 21:45 (https://bit.ly/2JobY6Z) we see that God promised many things to Israel and not one promise was broken. Everything he said came true.
So, whenever God promises you something in his word, remember that those promises will never be broken. If he said it then we can definitely believe it.
