Why is God called the God of Abraham, Isaac, and Jacob?

WHAT DOES THE BIBLE SAY?

The Bible refers to God as the God of Abraham, Isaac, and Jacob to emphasize His faithfulness across generations. God first promised Abraham blessings, land, and descendants (Genesis 12:1–3). That same promise was reaffirmed to Abraham’s son Isaac (Genesis 26:3–5) and then to Isaac’s son Jacob (Genesis 28:13–15). Naming all three highlights that God keeps His promises. One example of when this phrase is used includes when God visited Moses in the burning bush (Exodus 3:6, 15). Using it assured Israel that He was the same God who had bound Himself to their fathers and explained that He was saving them from captivity as part of keeping His promise. In another example, Elijah invoked the phrase when calling God to act publicly on behalf of His people (1 Kings 18:36). He was asking God to remember His promise. Later, Peter invoked the phrase to show that Jesus was God’s culmination of His promises (Acts 3:12–13). God’s faithfulness endures and His promises are sure. We can confidently place our hope in Him while sharing that hope with others.

FROM THE OLD TESTAMENT

• Before He formed Israel as a nation, God promised Abram that “I will make of you a great nation … and in you all the families of the earth shall be blessed” (Genesis 12:1–3). The title “God of Abraham” thus refers to this original promise.
• However, that promise did not end with Abraham. God reiterated it to Isaac, saying, “Sojourn in this land, and I will be with you and will bless you … and I will establish the oath that I swore to Abraham your father” (Genesis 26:3–5). The phrase “God of Abraham, Isaac …” thus signals that God was keeping His promise.
• Once again, God repeated the promise, this time to Jacob at Bethel: “I am the LORD, the God of Abraham your father and the God of Isaac … I will not leave you until I have done what I have promised you” (Genesis 28:13–15). Combined, these three men thus represent God’s promise being kept across generations. The implication is that He would continue to keep His promise into the future.
• When God later spoke to Moses, He said, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob” (Exodus 3:6). God then told Moses, “Say to the people of Israel, ‘The LORD … the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.’ This is my name forever” (Exodus 3:15). God was assuring both Moses and Israel that He was the same God who had given the original promise and that He was actively working it out through their delivery from slavery.
• Later, one of Israel’s prophets would pray, “O LORD, God of Abraham, Isaac, and Israel, let it be known this day that you are God in Israel .… Answer me, O LORD, answer me” (1 Kings 18:36–37). Elijah invoked that language not because God had forgotten His promise, but to show Israel that God would keep His promise despite her sin.

FROM THE NEW TESTAMENT

• Peter preached, “The God of Abraham, the God of Isaac, and the God of Jacob, the God of our fathers, glorified his servant Jesus” (Acts 3:13). Peter’s point was that the miracle of the healing that happened before this and the message about Jesus were not new works of God. Instead, they were works that continued the Old Testament promise thread, with Jesus being the culmination of His promise.
• With Jesus’ arrival, salvation was made available to all the nations of the earth (Galatians 3:8) and why Paul could refer to believers as all descendants of Abraham (Galatians 3:29). Just like Abraham had first believed God when He made the promise, so also now we are counted as righteous (Romans 4:5) when we believe in the culmination of that promise, Jesus.

IMPLICATIONS FOR TODAY

Being the God of Abraham, Issac and Jacob reminds us that God is faithful and working out His promises over time. In 2 Peter 3:8–9, we read about those who were wondering why Jesus had not yet returned, and Peter’s answer was to remind them of God’s faithfulness and desire to save people, which happens slowly over time. Allow his reply also to comfort you: God does not abandon His promises nor forget His people. It may take a long time from our view, but God is faithfully working out everything for good (Romans 8:28).

Let us ground our hope in this and share it with others. Jesus may be the culmination of God’s promises, but as long as history continues to move forward, the opportunity to take advantage of God’s offer through Him remains. So, share that hope with others while you can!

And, if you have not yet personally received Jesus as your Savior, know that God has promised that if you repent of your sin and trust in Jesus, God will count your faith as righteousness and will count Jesus’ death as having paid for your sin. When that happens, you will no longer be under condemnation but will be promised an eternal life of joy with God forever.
