Genesis chapter 21

1 Now the Lord was gracious to Sarah as he had said, and the Lord did for Sarah what he had promised.

Instead of laughing because she doesn't believe God, this time Sarah is laughing because she is so happy. The one thing she thought would never happen, was absolutely impossible, had come to pass and she was the mother of a baby boy, Isaac. Sarah had waited, and waited, and waited, trusting in God, probably doubting often as she was getting older each day, and yet God was faithful, despite her doubts, to fulfil what he had promised.

Sometimes, when we get overwhelmed by life, by the things happening around us, the problems, the troubles we have, it seems like there is no one there, that no one cares and we are having to do everything ourselves. Yet God is there in the midst of all of this turmoil, and he is faithful, no matter what we may think, what we may be going through and he is are work in our lives, just as he was at work in the lives of Sarah and Abraham. God is great, God is good, he is I Am, the Lord God Almighty, Jehovah Jirah, and the Lord will provide, despite our circumstances and because of our circumstances. He is El-Shaddai, the God who is sufficient for the needs of his people.

As is says in my study bible, the way to bring peace to a troubled heart is to focus on God's promises and to trust him to do what he says.

If God could give Sarah a baby when she was over 100, then why do we ever doubt he can give us what we need?
