GOD's Covenant part-2

Blessings to all,
Welcome again, I am Jerry, this portion of our study covers:

GOD’S COVENANT part 2

In the previous lesson we learned, as a sign of keeping this covenant, God had a new requirement for Abraham. He and every male of his household, born or bought, and every male in every generation to come, must be circumcised. This is the ritual removal of the foreskin. 

Those who were not circumcised would not be included in this covenant between God and Abraham's people. That's already a lot of change for one meeting, but God is not done yet. He truly surprises Abraham, telling him that Sarai's name must also be changed. She will now be known as Sarah, and she and Abraham would have a son after all. 

In reverence, or gratitude, or pure surprise, or perhaps all three, Abraham falls facedown and laughs. He's shocked at the mere suggestion of Sarah conceiving and bearing a child. Then Abraham has another thought: What about Ishmael?

God has already given a promise of blessing on Ishmael, spoken to his mother Hagar (Genesis 16:10–12). Here, though God will again promise to bless Ishmael abundantly, the covenant promises between God and Abraham will not pass through Ishmael. Instead, they will pass to Isaac, Abraham's yet-to-be conceived son with Sarah. 

That son will have been born by this time the following year. With that, God concludes His revelations and "leaves," at least symbolically giving Abraham an opportunity to make a decision. Abraham's head must have been spinning, but he did not hesitate to begin to obey God.

That very day, he went home and circumcised himself, Ishmael, and the hundreds of other males in his large company. Abraham's immediate obedience is further evidence that he was choosing to trust the Lord and to take Him at His word.

It is time to open our hearts, minds, and souls to the Word Of GOD.

Our scripture will be coming from:

Genesis 17:15-19 KJV 
[15] And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be.
[16] And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her.
[17] Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear?
[18] And Abraham said unto God, O that Ishmael might live before thee!
[19] And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
