Luke 1:73 Meaning and Explanation

The song reaches its bedrock: the oath which he sware to our father Abraham — the day God bound himself by his own word, promising blessing to all nations through Abraham's seed (Genesis 22:16-18).

God did not merely predict; he swore. An oath stakes the speaker's own name on performance, and God's name stands behind the blessing of the world through this seed. Christ is that oath being kept. No promise resting on the sworn word of God can fail.
