What does the Bible say about God's commandment to save?

The Bible presents God's commandment to save through passages like Psalm 71:3, where David expresses his trust in God's intervention. This notion is deeply rooted in the covenant of grace established within the Trinity, highlighting that God the Father commanded the Son to save His people, which aligns with the fulfillment of salvation through Jesus Christ. The commandment to save is not arbitrary; rather, it reflects God's omniscient and omnipotent nature, assuring that those whom He has chosen will be redeemed.
