There are some promises we cannot even fathom. In Exodus 3:21, God promises to do something that Moses surely must have questioned at least a tiny bit. At this point in time the Hebrews were slaves in Egypt. They were being abused. They were in no way looked at favorably. Why on earth would the Egyptians give anything of value to the Hebrew slaves?
Anyone in that situation would have found it hard to see something on a far different level. I am sure a homeless man living on a street corner would not believe someone who told them that in a few weeks they would be moving into a penthouse, or even that they would have a home at all. This seems as something impossible.
But we serve a God who does the impossible. God made this promise to Moses and later it would come true. The Egyptians wanted to be rid of the Israelites so badly. They gave them gifts. It happened just as God promised. Today, as things might look impossible—trust in the promises of God. Remember that He is a God of the impossible and if He has made a promise, He will see that it comes to be just as He said.
“And I will cause the Egyptians to look favorably on you. They will give you gifts when you go so you will not leave empty-handed.” – Exodus 3:21 [NLT]
