Genesis 21
The Lord visited Sarah as he had said, and the Lord did to Sarah as he had promised. 2 And Sarah conceived and bore Abraham a son in his old age at the time of which God had spoken to him. 3 Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac.[he laughs] 4 And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. 5 Abraham was a hundred years old when his son Isaac was born to him. 6 And Sarah said, “God has made laughter for me; everyone who hears will laugh over me.” 7 And she said, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
8 And the child grew and was weaned. And Abraham made a great feast on the day that Isaac was weaned. 9 But Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, laughing. 10 So she said to Abraham, “Cast out this slave woman with her son, for the son of this slave woman shall not be heir with my son Isaac.” 11 And the thing was very displeasing to Abraham on account of his son. 12 But God said to Abraham, “Be not displeased because of the boy and because of your slave woman. Whatever Sarah says to you, do as she tells you, for through Isaac shall your offspring be named. 13 And I will make a nation of the son of the slave woman also, because he is your offspring.” 14 So Abraham rose early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder, along with the child, and sent her away. And she departed and wandered in the wilderness of Beersheba.
15 When the water in the skin was gone, she put the child under one of the bushes. 16 Then she went and sat down opposite him a good way off, about the distance of a bowshot, for she said, “Let me not look on the death of the child.” And as she sat opposite him, she lifted up her voice and wept. 17 And God heard the voice of the boy, and the angel of God called to Hagar from heaven and said to her, “What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is. 18 Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation.” 19 Then God opened her eyes, and she saw a well of water. And she went and filled the skin with water and gave the boy a drink. 20 And God was with the boy, and he grew up. He lived in the wilderness and became an expert with the bow. 21 He lived in the wilderness of Paran, and his mother took a wife for him from the land of Egypt.
22 At that time Abimelech and Phicol the commander of his army said to Abraham, “God is with you in all that you do. 23 Now therefore swear to me here by God that you will not deal falsely with me or with my descendants or with my posterity, but as I have dealt kindly with you, so you will deal with me and with the land where you have sojourned.” 24 And Abraham said, “I will swear.”
25 When Abraham reproved Abimelech about a well of water that Abimelech's servants had seized, 26 Abimelech said, “I do not know who has done this thing; you did not tell me, and I have not heard of it until today.” 27 So Abraham took sheep and oxen and gave them to Abimelech, and the two men made a covenant. 28 Abraham set seven ewe lambs of the flock apart. 29 And Abimelech said to Abraham, “What is the meaning of these seven ewe lambs that you have set apart?” 30 He said, “These seven ewe lambs you will take from my hand, that this[you] may be a witness for me that I dug this well.” 31 Therefore that place was called Beersheba, because there both of them swore an oath. 32 So they made a covenant at Beersheba. Then Abimelech and Phicol the commander of his army rose up and returned to the land of the Philistines. 33 Abraham planted a tamarisk tree in Beersheba and called there on the name of the Lord, the Everlasting God. 34 And Abraham sojourned many days in the land of the Philistines.
Luke 7:6-10
6 And Jesus went with them. When he was not far from the house, the centurion sent friends, saying to him, “Lord, do not trouble yourself, for I am not worthy to have you come under my roof. 7 Therefore I did not presume to come to you. But say the word, and let my servant be healed. 8 For I too am a man set under authority, with soldiers under me: and I say to one, ‘Go,’ and he goes; and to another, ‘Come,’ and he comes; and to my servant, ‘Do this,’ and he does it.” 9 When Jesus heard these things, he marveled at him, and turning to the crowd that followed him, said, “I tell you, not even in Israel have I found such faith.” 10 And when those who had been sent returned to the house, they found the servant well.
We clearly remember Jesus was overwhelmed with the faith of the centurion. There is wonder and awe in the miracle of Sarah and Abraham's son. So much so, God Himself visits.
Genesis 15:5
And he brought him outside and said, “Look toward heaven, and number the stars, if you are able to number them.” Then he said to him, “So shall your offspring be."
This was a miracle indeed. And once again the way, the truth and the life are not strewn with roses. We are like the people who followed Jesus into the wilderness and He says to so many, what do you want from me?
Sarah, with her longed for son, is displeased over laughter. And the thing was very displeasing to Abraham.
1 Timothy 1:15
The saying is trustworthy and deserving of full acceptance, that Christ Jesus came into the world to save sinners
Mark 2:17
On hearing this, Jesus said to them, "It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but sinners."
Again and again the Scriptures point out - none of the characters were perfect, none had an easy path. And God continued to move them down the path He had for them. You have to wish they all could be more compassionate to one another.
Giving credit were credit is due, Abimelech, has none of the usual 'Philistine" characteristics. Abraham is blessed in Abimelech understanding Abraham has the blessing of God Almighty. Abraham and Abimelech have a spirit of willingness to have peace, as a foreshadowing of Jesus the Savior to all nations He has created.
Matthew 5:9
Blessed are the peacemakers, for they will be called sons of God.
Matthew 9:13
But go and learn what this means: 'I desire mercy, not sacrifice.' For I have not come to call the righteous, but sinners."
Hebrews 11:8-12
8 By faith Abraham obeyed when he was called to go out to a place that he was to receive as an inheritance. And he went out, not knowing where he was going. 9 By faith he went to live in the land of promise, as in a foreign land, living in tents with Isaac and Jacob, heirs with him of the same promise. 10 For he was looking forward to the city that has foundations, whose designer and builder is God. 11 By faith Sarah herself received power to conceive, even when she was past the age, since she considered him faithful who had promised. 12 Therefore from one man, and him as good as dead, were born descendants as many as the stars of heaven and as many as the innumerable grains of sand by the seashore.
