“Because God wanted to show his unchangeable purpose even more clearly to the heirs of the promise, He guaranteed it with an oath, so that through two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to seize the hope set before us. We have this hope as an anchor for the soul, firm and secure.”
An anchor of the soul—both firm and secure because of two immutable things. Two things that remain unchanged and unchangeable: the word of God and a promise from God to confirm His word. These two things are unchanged and unchangeable because it is impossible for God to lie.
God could have just given His word, but He wants to give us strong encouragement, so He gives us precious and powerful promises as well. He wanted to give Abram strong encouragement too, as we see in Genesis 15. God gives Abram His word and then God confirms His word with a covenant so that Abram would have hope grounded in God like an anchor of the soul.
What was the word and what was the promise? Listen to our study in Genesis 15 and receive the same strong encouragement Abram received as the Lord met him.
