Genesis chapter 18

13 Then the Lord said to Abraham, Why did Sarah laugh and say, 'Will I really have a child, now that I am old?'
14 Is anything too hard for the Lord? I will return to you at the appointed time next year and Sarah will have a son.
15 Sarah was afraid, so she lied and said, I did not laugh. But he said, Yes, you did laugh.

When we are caught out in something, the natural reaction is to lie, to cover up, to pretend that we didn't do it, say it. Here, Sarah displays all of these as she is caught out laughing to herself when she hears that this time next year she will have a baby. After all, she was 90 years old at this point and Abraham was 100, so it is understandable that she maybe thought it was all one big joke.

Yet the Lord hears this, just as he hears everything, and he asks Abraham "is anything too hard for the Lord?"

There are times when it is difficult to believe, to have faith, to really trust God that things will work out. It is easy to sink into a depression, to become some downcast, worried and anxious that it seems like you are in one big black pit that just keeps getting deeper and deeper. Yet God never changes, He is the God of yesterday, today and tomorrow. He created the universe, the sun, moon and stars out of nothing. Jesus spoke the world into existence and the Holy Spirit moved across the waters (Genesis 1). If we truly believe in the existence of God, of His Son, Jesus Christ, and in the Holy Spirit, then we have to realise that a God who can create all that we see around us from nothing is more powerful than we can ever imagine. There is nothing that he cannot do, and nothing can stop him from doing whatever he wants.

Nothing, absolutely nothing, is too hard for the Lord.
