What role does faith play in the covenant of promise?

In the context of the covenant of promise, faith is not viewed as a condition we must fulfill to receive salvation but rather as a gift that God gives His elect. Ephesians 2:8 highlights that faith itself is a divine grant, stating, 'For by grace you have been saved through faith, and that not of yourselves; it is the gift of God.' Thus, just as Christ's work fulfills the law, our faith in Him points to His righteousness. Galatians 3:26 declares that through faith in Jesus Christ, we become children of God, illustrating that faith is the means by which we lay hold of the spiritual blessings procured by Christ.
