Keeping His Promise     Gen. 21:1-8     Nov. 15, 2015


When you have been a Christian very long you understand our God is a promise keeping God.  The more

you read the Bible the more you know God has kept His promises over a long period of time.  We can read of promises that were fulfilled after hundreds of years.  Some of the promises are; It will rain 40 days and nights, Abraham will have a son when he is 100, God will bring the children of Israel out of Egypt, they will march in the wilderness for 40 years, They will march through the Red Sea, and settle in the Promised Land.  There are hundreds more and today we can look forward to the promise of Jesus’ return and know it will happen because God is Keeping His Promise.



1.   God Keeps His Promise A . . Son Is Born.   21:1-2

A.   A Son Is Born . . As Promised.   21:1

1 The Lord came to Sarah as He had said, and the Lord did for Sarah what He had promised.


B.    A Son Is Born At The . . Appointed Time.   21:2

2 Sarah became pregnant and bore a son to Abraham in his old age, at the appointed time God had told him.


           Most people with biblical knowledge know Abraham and Sarah were promised a son when they were past the age of having children.  But God gave a promise, and when they were 90 and 100 years of age God provided their child.  Sarah and Abraham were given a promise they would receive a son at an appointed time. 

God promised this son would be blessed in many ways as he would be a blessing to the Jewish Nation and be an important part of a linage that would bring Jesus the Messiah.



2.   God Keeps His Promise A . . Son Is Named.   21:3-7                          `

A.   A Son Is Named Isaac and . . Circumcised on the Eight Day.      21:3-4

3 Abraham named his son who was born to him—the one Sarah bore to him—Isaac.

4 When his son Isaac was eight days old, Abraham circumcised him, as God had commanded him.


B.    A Son Is Named and Sarah . . Celebrated and Laughed.      21:5-6

5 Abraham was 100 years old when his son Isaac was born to him.

6 Sarah said, "God has made me laugh, and everyone who hears will laugh with me."


Most men who have sons specifically looked forward to naming them.  God chose the name for this son born to Sarah and Abraham.  God said his name would be Isaac.  The name means, “laughter”.   Abraham laughed in disbelief when God told him he would have a child with Sarah. Sarah laughed after the birth of Isaac and several laughed with her.  The birth of Isaac was a joyous occasion.  To recognize his obedience and appreciation of God’s provided son Abraham named the boy “Isaac”.  He was circumcised just as God directed.  All of these acts of obedience were a joy and privilege to fulfill for Abraham and Sarah.



3.   God Keeps His Promise A Son Is . . Cradled and Nursed.   21:7-8

A.   A Son Is . . Cradled and Nursed.  21:7

7 She also said, "Who would have told Abraham that Sarah would nurse children? Yet I have borne him a

son in his old age."


B.    A Son Is Cradled and Nursed and . . Celebrated on this day.      21:8

8 The child grew and was weaned, and Abraham held a great feast on the day Isaac was weaned.


Most women know the joy of holding and cradling their baby.  Many ladies nurse their babies and

claim a joy at this process as it gives an added bond to mother and child.  I have heard the distance between a ladies breasts and her eyes is about 18 inches and that is as far as a babies eyes will see clearly.  So Isaac saw his mother often when he was a small baby.   Abraham called for a great feast when Isaac was weaned.  All of the progressive events of Isaac’s life caused this couple to have a time of celebration for he was a special child.

God planned for His birth and in Isaac He was Keeping His Promises.  Amen?  Amen!
