Ecclesiastes 5:3-7, Genesis 15:5, 22:7-8, 15-19. By faith, Abraham found confidence in God. He had the faith, God will come through, and by providing first a son at his old age with his sterile wife Sarah. And a great descendant as abundant stars and the sand in the seashore. God is sovereign he sees our heart when making a vow we are to fulfill that vow by faith and confidence that we will receive more than what we are offering.
