Isaac The Fulfillment Of God’s Promise

Isaac Is Born


Isaac Is Born


Isaac is a beautiful picture of sonship, what it means to be a child of God. If ever a boy was spoiled and pampered by his father, it was Isaac. He is the darling of his father’s heart. I doubt that any message could be more welcome today than the one that is so beautifully exemplified in Isaac: that God loves us, values us, and calls us the darlings of His heart. “Dear friends, now we are children of God,” says 1 John 3:2, “what we will be has not yet been made known. But we know that when he appears, we shall be like him.” We shall be like Christ.


Few under the Old Testament were brought into the world with such expectations as Isaac. The coming of Isaac into their home brought both sorrow and joy to Abraham and Sarah. He was in this a type of Christ, that Seed which the holy God so long promised, and holy men so long expected. He was born according to the promise, at the set time of which God had spoken. As you look at the persons involved in this important event, you can learn some valuable lessons about basic Christian doctrine and how to live the Christian life.


Abraham and Sarah: Faith and Promise

God visited Sarah exactly as he said he would; God did to Sarah what he promised: Sarah became pregnant and gave Abraham a son in his old age, and at the very time God had set. Abraham named him Isaac. When his son was eight days old, Abraham circumcised him just as God had commanded.

Abraham was a hundred years old when his son Isaac was born.
Sarah said,

God has blessed me with laughter
and all who get the news will laugh with me!


She also said,


Whoever would have suggested to Abraham
that Sarah would one day nurse a baby!
Yet here I am! I’ve given the old man a son!


Genesis 21:1-7 (MSG)


Sarah had borne the burden of childlessness for many years, a heavy burden indeed in that culture and at that time. People must have smiled when they heard that her husband’s name was Abraham, “father of a multitude.” He was the father of one son, Ishmael, but that was far from a multitude; and Sarah had never given birth. But now all of her reproach was ended, and they were rejoicing in the arrival of their son.


But the birth of Isaac involved much more than parental joy, for his birth meant the fulfillment of God’s promise. When God had called Abraham, He promised to make of him a great nation that would bless the whole world (Gen.12:1-3). Then He repeatedly promised to give the land of Canaan to Abraham’s descendants (Gen. 17:7) and to multiply them greatly (Gen. 13:15-17). Abraham would be the father of the promised seed (Gen. 15:4), and Sarah (not Hagar) would be the mother (Gen. 17:19; 18:9-15). The birth of Isaac reminds us that God keeps His promises, in His own way, and in His own time. In spite of their occasional failures, Abraham and Sarah believed God; and God honored their faith (Heb. 11:8-11).


Isaac’s birth also meant the rewarding of patience. Abraham and Sarah had to wait twenty-five years for their son to be born, because it is “through faith and patience [we] inherit the promises” (Heb. 6:12). Trusting God’s promises not only gives you a blessing at the end, but it gives you a blessing while you are waiting. Just as Olympic athletes develop their skills as they practice hard and long before the big event, so God’s children grow in godliness and faith as they wait for the fulfillment of God’s promises. Faith is a journey, and each happy destination is the beginning of a new journey. When God wants to build our patience, He gives us promises, sends us trials, and tells us to trust Him (James 1:1-8).


When God wants to build our patience, He gives us promises, sends us trials, and tells us to trust Him.

In this past year I have had to endure many trials with my business. The lesson I now see is this.... by going through the trial rather than avoiding it or running the other way, the Lord taught me how to be patient and wait on Him. Sometimes He had me wait two weeks to respond to either an email or phone call.

What I discovered was when I obeyed the Lord everything fell into place and worked out the way God intended not the way I thought it should go.

The biggest blessing when I obeyed God was I had a peace beyond understanding knowing God was in charge and I didn't have to be.

Thank You Jesus!

The birth of Isaac was certainly the revelation of God’s power. That was one reason why God waited so long: He wanted Abraham and Sarah to be “as good as dead” so that their son’s birth would be a miracle of God and not a marvel of human nature (Rom. 4:17-21). Abraham and Sarah experienced God’s resurrection power in their lives because they yielded to Him and believed His Word. Faith in God’s promises releases God’s power (Eph. 3:20-21; Phil. 3:10), “for no word from God shall be void of power” (Luke 1:37).


Finally, the birth of Isaac was a step forward in the accomplishing of God’s purpose. The future redemption of a lost world rested with a little baby boy! Isaac would beget Jacob, and Jacob would give the world the twelve tribes of Israel; and from Israel the promised Messiah would be born. Down through the centuries, some of the “living links” in the chain of promise may have seemed insignificant and weak; but they helped to fulfill the purposes of God.


You may wonder if what you do is really important to God and His work in this world; but it is, if you are faithful to trust His Word and do His will. The next time you feel defeated and discouraged, remember Abraham and Sarah; and remind yourself that faith and promise go together. God keeps His promises and gives you the power you need to do what He wants you to do. No matter how long you may have to wait, you can trust God to accomplish His purposes.
