In Genesis 12, God made a covenant promise to Abraham which foretold God’s purpose to bless all the families of the earth. “And in you all the families of the earth shall be blessed.” (vs. 3)
Abraham was known to be a prototypical “father of faith.” In scripture Abraham is designated as the “father” of all who walk his pathway of faith. God blessed Abraham in many ways, including material blessings.
In Galatians 3:13, 14 God promises to give all believers “the blessing of Abraham,” telling us that Jesus became a curse for us, so that we might receive “the blessing of Abraham.” This blessing begins, of course, with our being born again, or becoming new creatures in Christ Jesus. But “the blessing of Abraham” involves other things as well. The Lord wants us to prosper—spiritually, emotionally, physically, and materially. Abraham’s blessing is ours by His promise.
It was Abraham’s faith by believing God’s promise that God counted him to be righteous. (Romans 4:3) We too, are justified (made righteous) by our faith and not by works or our own efforts that would compel God to accept us. Romans 3:13 says “God’s promise to give the whole earth to Abraham and his descendants was based not on obedience to God’s law, but on a right relationship with God that comes by faith.
Believing in God means acknowledging our unworthiness and depending entirely on God’s mercy. Galatians 3:9 says, “So then those who are of faith are blessed with believing Abraham.”
To have faith, there must be an object. The object of our faith is the blood of Christ which alone joins people to God and entitles them to God’s covenant provisions. It is the shed blood of Christ that satisfied God’s justice upon our sin and is now forever the only means of right relationship with the holy God. It is through faith in the blood of Christ that we are justified in God’s eyes!”
Abraham is called the “Father of Faith” because he believed God’s covenant promise for salvation through faith even centuries before the law was given. We are blessed with Abraham for believing our salvation is received by faith in Christ’s redemptive blood that he shed upon the cross 2000 years ago.
