What does the Bible say about God keeping His promises?

In Numbers 23:19, Balaam declares, 'God is not a man that he should lie, neither the son of man that he should repent. Hath he said, and shall he not do it?' This underscores the truth that while humans often fail to keep their promises, God remains faithful and unchangeable. His word is dependable, and whatever He has promised, He will accomplish. This principle is echoed throughout Scripture, reminding believers that God’s faithfulness applies not only to Israel in the Old Testament but to all of His chosen people throughout ages.
