And the LORD visited Sarah as He had said, and the LORD did unto Sarah as He had spoken. Genesis 21:1
The LORD had promised Abraham and Sarah that they would have a son. God had promised them that Abraham would be a father of nations, and through him all the world would be blessed (Genesis 12:3). Much time had passed when this promise is fulfilled.
At the age of 86 Abraham had gone along with the scheme of Sarah to have a son with Hagar. This was not what God had promised. Maybe in concocting this plan Sarah thought they would be fulfilling the will of God. God’s promise to Abraham for a son was for Sarah too.
When Abraham was 100 years of age, and Sarah was 99 the promise of God was fulfilled. Sarah gave birth to Isaac which means “Laughter”, because she had been laughing. Just as nothing was too hard for God to do for Abraham and Sarah (Genesis 18:14), so it is for the Christian today. Also for the lost soul to receive forgiveness and peace and rest.
When God the LORD shows up He will do all that He has said.
He has told us that He loved us so much that He gave us His only begotten Son, that whosoever believes in Him shall not perish but have everlasting life (John 3:16). That Son is Jesus Christ who died on the cross, was buried, and He rose again. That is the LORD’S visit today. Call on His name repent and believe.
