12 “Sarah your wife will have a son.”

 Genesis 18:10

 God promised Abraham that he and Sarah would be the founders of a great nation and kings would be born from them in the future. Abrahm and Sarah found this very hard to believe because they were naturally past child-bearing years by a long way. They tried their own way to solve the problem and Ishmael was born but God said that he was not the son of promise. The line of the Messiah would be from Isaac.

 Abrahma and Sarah both laughed at the prospect of having a child in their old age but God was faithful. (Genesis 17:17. Genesis 18:12) God works according to His covenant and not according to the ways of the world. He delights to work contrary to human expectations and carries out His will according to His own purposes.

 God also promised another Son of promise, even our Lord Jesus Christ.

“Therefore the Lord himself will give you a sign. Behold, the virgin will conceive, and bear a son, and shall call his name Immanuel.”

 Isaiah 7:14

 As Isaac was predicted so was our Lord Jesus 500 years before He was born, indeed the promises go back to the beginning of Genesis. Let us rejoice at the provision of the Lord and wonder at His ways.
