"On God rests my salvation and my glory; my mighty rock, my
refuge is God" (Psalm 62:7). "So when God desired to show more
convincingly to the heirs of the promise the unchangeable character
of His purpose, He guaranteed it with an oath, so that by two
unchangeable things, in which it is impossible for God to lie, we
who have fled for refuge might have strong encouragement to hold
fast to the hope set before us. We have this as a sure and
steadfast anchor of the soul" (Hebrews 6:17-19).
