The God of Abraham, and of Isaac, and of Jacob
Some 30 times, these three patriarchs are named together in the Bible. Over half of those times, God identifies Himself as each of their God, by name. God also identifies Himself as the God of our fathers (they BEING Abraham, Isaac, and Jacob) over 100 times.
What is it that God is revealing to us as He says this? Well, Abraham was the first man to exhibit faith in God. God told him to sacrifice Isaac, and he intended to obey. He must have had faith that either God would spare Isaac or bring him back from death. Whichever way he thought God could act, he had faith that God would, and God counted it to Abraham for righteousness. He was justified by faith, and in fact, was shown Jesus’s day, and found joy.
Isaac was the son that God told Abraham He would give to him and Sara. Isaac was the fulfillment of God’s promise to them. What God says He will do, He WILL do, and so he did. This was a key to why Abraham found faith in God. He was asked to sacrifice the promise.
Jacob was the father of the nation Israel, whom the nation is named after. The Bible refers to him as one or the other. He is referred to as Jacob when he is in the wrong, in his flesh, making decisions based from a worldly point of view, and in essence, rebelling against God. He is called Israel when he is God’s man through and through, walking with God, in His Will.
So, this is what God is saying when He calls Himself the God of Abraham, and of Isaac, and of Jacob:
He is the God who finds us justified in our faith, Who keeps His promises, and Who will remain our God even as we fail Him or sin against Him.
This is our loving Father, and as Jesus told us, “he that has seen Me has seen the Father“. Jesus lived His life here perfectly, loving all and treating others with dignity. Correcting as needed, always sharing Truth, and ultimately saving us all from ourselves. Jesus showed us what faith is, He is the fulfillment of God’s greatest Promise, and He dwelt amongst sinners.
Isn’t this the perfect image of the God of Abraham, Isaac, and Jacob? He still lives among us, the sinners, and He is the God of the living, not the dead, and so as He proclaims to us that He is the God of Abraham, Isaac, and Jacob, not was, He is telling us that the patriarchs yet live. (Mark 12:26&27) He does keep His Promises, and it is by His hand that we will one day see glory and live with Him eternally, even if we occasionally stumble, for He is the God of Abraham, and the God of Isaac, and the God of Jacob, and the God of all of us sinners.
