This text tells us two things about God. First, the God of the Bible is the only God that can give us deliverance from oppressive situations. Second, God wants to give us more than what we have. This means that we should never think that we have enough from God. That is why God says to his people, “open wide your mouth and I will fill it” (v 10). God can do great things for us. He proved to Israel that he has power to do awesome things. What we need to do as his people is to believe God and ask for fullness. The Lord wants us to have large expectations of him because he is able to fill every want with plenty. The only limitation to the promise of God is our lack of faith. Our God is a God of overflowing grace, always ready to meet our need.
