“And God said to Abraham, As for Sarai your wife, you shall not call her name Sarai, but Sarah (Princess) her name shall be.” Genesis 17:15 Amplified
As we continue our study of the women of the Bible we return to Sarai, but now the Lord has changed her name to Sarah, meaning Princess. He also changed Abram’s name to Abraham. After telling Abraham of the name changes God tells him that he will have a son from Sarah. Abraham finds this hard to believe, wouldn’t we, as he is 99 years old and Sarah is 90 years old. Genesis 17:17 says that he falls down laughing about it. So God tells Abraham that will be the child’s name, laughter, or Isaac.
In Genesis 18:12, Sarah hears the Lord telling Abraham again about her becoming pregnant and SHE laughs. God responds by saying, Is anything too hard or too wonderful for the Lord? Sarah denied that she laughed because she was afraid, but the Lord told her He knew she did.
Why do we doubt the Lord, especially when it’s something we want? Sarah certainly wanted a child, that was a badge of honor for a woman, to have children. Likewise it was a badge of dishonor to be barren. To me, she looked at the facts and we let the facts blind us to faith as well sometimes. She was 90 years old and normally a woman of her age couldn’t have children. She had likely stopped having her monthly cycle because it says in verse 11, it ceased to be with Sarah as with young women. It takes an egg and sperm to make a baby right? Not with God! We jump ahead to chapter 21 and Sarah delivers her son to Abraham and says in verse 6 & 7, “And Sarah said, God has made me laugh, all who hear will laugh with me. Who would have said to Abraham that Sarah would nurse children at the breast? For I have borne him a son in his old age!”
This speaks to me that we are never too old for God to use us, we just need to make ourselves available, and laugh.
