(Isaiah 55: 8- 11)
Abraham was seventy-five years old when God called him to leave his country, relatives and his father’s house to a land He was going to show him. He promised to make a great nation from him and bless him with riches. Seventy-five in those days was still a young age, relatively speaking, for his father had died at the age of 205. He had no children at that time, for his wife was barren. When the Lord appeared to Abraham in a vision a second time, he said to the Lord God, What can You give me, since I am going on childless and he who shall be the owner and heir of my house is this Eliezer of Damascus? Look, You have given me no child; and born in my house is my heir. Abraham in his human nature is puzzled, not understanding God’s time line for the fulfillment of His promise. Sixteen years later, God came to Abraham again and this time he made a covenant between Him and Abraham. This covenant was that Abraham shall be the father of many nations; he probably wondered when, since sixteen years had passed since God had called him out of his land to a new land He was going to give him but his wife still was barren.
When God came to Abraham the last time before his wife conceived, he was at the age one hundred and his wife at ninety years old. God’s promise of a son became a matter of laughter to both of them. But God assured them that time that He was going surely to return to them when the season had come round, and behold, Sarah his wife was going to have a son. The reality to them was that they were now old, well advanced in years; it had ceased to be with Sarah as with women. Therefore Sarah laughed to herself, saying, After I have become aged shall I have pleasure and delight, my lord being old? The Lord saw and heard Sarah and said, Is anything too hard or too wonderful for the Lord? At the appointed time, when the season comes around, I will return to you and Sarah shall have borne a son (Gen.17,18:10-14). God’s thoughts are not our thoughts; our ways are not His ways!
The Lord visited Sarah as He had said, and the Lord did for her as He had promised (Gen. 21:1). Abraham was one hundred and Sarah ninety years old; but what is it to the Lord, since He is the Creator of life, and He is not in a frame of human time? He opened the womb of Sarah and what seemed impossible to them and their family, and a matter of laughter, became an expression of God’s power and faithfulness, for there is nothing hard for Him. His thoughts are not our thoughts; our ways are not His ways. He could have called someone younger according to our thoughts and reasoning; or He could have given Abraham a son earlier, but how would they have known the depth of God’s power and wisdom in the fulfilling of His promise to them? In our weakness God’s strength is manifested. Abraham had to go through a few experiences in life before he would see the reality of the promises. First he had to believe in the only true God, since he had come from a family of idol worshippers; second, he had to have faith to take the first step in obedience to God. Faith and obedience were then credited to him, for doing the impossible as far as to obey God in sacrificing his only son as God had asked of him to do. He had waited for that son twenty-five years. Now the Lord wanted to take him back. The depth of his faith went beyond the visible reality; in his faith he obeyed, believing God was going to give him his son back after he had killed him, as we read in Hebrews 11:17-18: By faith Abraham, when he was put to the test, had already brought Isaac for an offering; he who had gladly received all welcomed [God’s] promises was ready to sacrifice his only son, of whom it was said, through Isaac shall your descendant be reckoned, for he reasoned that God was able to raise [him] up even from among the dead. Indeed in the sense that Isaac was figuratively dead, he did receive him back from the dead. “God’s thoughts are not our thoughts; our ways are not God’s ways”!
