21 The Lord was gracious to Sarah, just as he had said he would be. The Lord did for Sarah what he had promised to do. 2 Sarah became pregnant. She had a son by Abraham when he was old. The child was born at the exact time God had promised. 3 Abraham gave the name Isaac to the son Sarah had by him. 4 When his son Isaac was eight days old, Abraham circumcised him. He did it exactly as God had commanded him. 5 Abraham was 100 years old when his son Isaac was born to him. 6 Sarah said, “God has given laughter to me. Everyone who hears about this will laugh with me.” 7 She also said, “Who would have said to Abraham that Sarah would breast-feed children? But I’ve had a son by him when he is old.”
Who would expect a 100 year old man to have a baby boy born to him? But then nothing is impossible to God! Because He is the Sovereign Lord, He chose to perform such a miracle.
Two things stand out so clearly in this reading.  the complete dependability of our God…..He did exactly as He said He would  His promises are equally dependable….God did to Sarah what He promised.
This is an event which touches my life and yours. To re-affirm that our Father God is absolutely reliable is so special in a world which so often fails to deliver its promises. In my daily life I know His promises are firmly established as part of my life and I am convinced that they will be fulfilled in His time.
There was a special purpose in Isaac’s birth at this late time in his parents’ life. He was to continue the covenant relationship which God had set up with Abraham. The principle here can be applied to everyone of us as we pursue our daily walk with Him.
Our hearts are full of praise because you have shown us just how dependable you are. We ask you Holy Spirit to continue to re-affirm your faithfulness in every situation of our lives.
