Abraham, Sarah, and Isaac
When Abram was ninety-nine years old, God appears to Abram and says, "I am the Almighty God, walk before Me and be thou perfect. I will make My covenant with thee; I will multiply thee; I will make thee exceedingly fruitful; I will make nations of thee; I will establish My covenant with thee and thy seed; I will give unto thee and thy seed this land, and I will be their God." God changed his name from Abram (High father) to Abraham (Father of many nations). God planned one child for him, but he married Hagar and Kiturah. Again He said to Abraham, "I will give you a son of Sarah", and Abraham laughed at the idea. (Gen.17:17).
The Lord appeared unto Abraham as he sat in his tent door. He recognized Him and welcomed Him and asked Him to sit down while he went for water to wash His feet and for food for Him to eat and he said to Him: "Comfort ye your hearts...for therefore are ye come unto me". (Gen.18:5). And then He tells Abraham again that Sarah is to have a child, and she laughs at the idea and she denies that she laughed.
After Abraham had patiently endured, he obtained the promise.(Heb.6:15)."Who against hope believed in hope, and being not weak in faith, he considered not his own body now dead , about an hundred years old, neither yet the deadness of Sarah's womb, he staggered not at the promises of God through unbelief: but was strong in faith, giving glory to God: and being fully persuaded that, what He had promised, He was able also to perform.(Rom.4:18-21). "And through faith also Sarah herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged Him faithful who had promised." (Heb.11:11). God saw the faith that was in the heart of Abraham and Sarah and God accepted their faith and fulfilled the promise that He had made them. It had been twenty-five years since they had come into the land: but now they were able to hope against hope. Even though they saw no way for God to give them a son, He said that He would and they now believed Him.When this baby was born, according to the word of the Lord, Abraham called his name Isaac (Gen.21:3) and that name means laughter. And Abraham was happy and thankful and Sarah said,"God hath made me to laugh."(Gen.21:6).
"It came to pass after these things, that God did test Abraham, and said unto him, Take now thy son, thine only son, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt-offering upon one of the mountains which I will tell thee of." (Gen.22:1-2). This was the son of whom it was said, "In Isaac shall thy seed be called". (Heb. 11:18). (Gen.21:12). Abraham had been called upon to give up his country, his kindred, (his father and Lot), Ishmael and now Isaac. Abraham rose up early in the morning, and saddled his ass and took two of his young men with him and Isaac his son, and clave the wood for the burnt-offering, and rose up, and went unto the place of which God had told him. And on the third day Abraham lifted up his eyes, and saw the place afar off. And Abraham said unto his young men, Abide ye here with the ass; and I and the lad will go yonder and worship, and come again to you.
What faith Abraham had! He fully expected to offer Isaac as a burnt-offering unto the Lord, but he also just as fully expected God to raise him from the dead! Abraham carried the fire and the knife and he laid the wood upon Isaac and together they went up the mountain. Isaac said, Where is the offering? And Abraham answered, My Son, God will provide HIMSELF a Lamb for a burnt-offering. This is the first time that the word lamb is used in the Bible in the singular and the first time it is used in the New Testament is, "Behold the Lamb of God that taketh away the sin of the world". (Jn.1:29). When Abraham was about to do the deed God sent and Angel to stop him because he had proved his faith. He released Isaac and they saw a ram caught in the bushes which they sacrificed. "Because thou hast done this thing, and hast not withheld thy son, thine only son: that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of heaven and thy seed shall possess the gate of his enemies, and in thy seed shall all the nations of the earth be blessed: because thou hast obeyed My voice." (Gen.22:16-18).
