at the very time God had promised him Gen 21:2
Story: The Lord was gracious to Sarah as he had said when she was 90 years old, and the Lord did for Sarah what he had promised. Sarah became pregnant and bore a son to Abraham in his old age, at the very time God had promised him. This is written as is in the Genesis 21
Lesson: Even in the worst situation, when Lord is gracious the miracle will happen. Though it looks hopeless, His promises will be fulfilled. Lord who set the time for earth to rotate and revolve, His timing for His promise will be perfect. So issue is not the delay, but it is our patience. Lesson to learn is faith and not to fall into fear.
Prayer: Father Lord, when I do not see things working in my way, I get anxious. Teach to trust in the perfect timing of the Almighty God. Amen.
