Constitution: Proverbs 19:21 There are many plans in a man's heart, nevertheless the Lord's counsel, that will stand.
Focus: The Book of Genesis in the Constitution describes both God's promise to Abraham and Sarah that they would have a son, and Sarah's frantic effort to assist God in achieving that purpose when the years roll by and she had not yet given birth to a son. She gave her handmaiden to her husband Abraham. She hoped to have a son through her. But keep in mind that God said she would have a son. Now when Hagai conceived and bore a son, Abraham named him Ishmael. Abraham tried to make him the promised son. But the Lord did not accede to his wishes. The Lord had promised Abraham a son through his wife Sarah, and that remained God's promise, because His purpose as revealed in His covenant with Abraham was that Sarah would be the mother of the promised son.
Constitution: Genesis 17:17-22 Then Abraham fell on his face and laughed, and said in his heart, "Shall a child be born to a man who is one hundred years old? And shall Sarah, who is ninety years old, bear a child?" 18) And Abraham said to God, "Oh, that Ishmael might live before You!" 19) Then God said: "No, Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My covenant with him for an everlasting covenant, and with his descendants after him. 20) And as for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He shall beget twelve princes, and I will make him a great nation. 21) But My covenant I will establish with Isaac, whom Sarah shall bear to you at this set time next year." 22) Then He finished talking with him, and God went up from Abraham.
The closer you stay to the Lord in prayer, fasting, reading and studying the Word; the sooner your purpose will be revealed to you.
