One Good Reason to Endure
What is the faithfulness of God?
The doctrine that God will always do what he has said and fulfill what he has promised. (12B.5)
5. Truthfulness (and Faithfulness). God’s truthfulness means that he is the true God, and that all his knowledge and words are both true and the final standard of truth.
God’s faithfulness means that God will always do what he has said and fulfill what he has promised (Num. 23:19; cf. 2 Sam. 7:28; Ps. 141:6; et al.). He can be relied upon, and he will never prove unfaithful to those who trust what he has said. Indeed, the essence of true faith is taking God at his word and relying on him to do as he has promised.
