I have always thought that kids are collectively closer to God than most adults. The older one gets it is far too easy to become cynical, having had a bevy of expectations and/or dreams squished in the press of life. But kids tend to not have that kind of history. They simply believe.
Maybe Abraham was a kid at heart. When God gave him a promise that it would be through his son Isaac and not anyone else that the great spiritual inheritance would be passed on, Abraham simply believed. In fact, he was so thoroughly convinced that God was good for his word that even when the most contradictory of circumstances seemed to warrant that it was not going to come to pass, he still believed.
At the heart of genuine authentic biblical faith is the simple unshakable conviction that one can completely bank his/her life on the promises of God. So, even when God came along and told Abraham to sacrifice Isaac, child-like Abram just reasoned that even if his son were dead, God would just do the most impossible thing of all by resurrecting his lifeless body.
Abraham is the father of all who believe not because he always did the right thing and never stumbled. He is our spiritual ancestor because of his simple faith placed firmly in the God whom he believed could do the impossible. It is faith that ought to dictate how we pray and how we go about living. It is faith that really should determine how we make decisions and how churches should lay plans. And it is faith in the promises of God which ought to cause us to respond to him like a little child.
God of the impossible, you are the one who fulfills every good word in and through Jesus Christ. I trust you, that as I proclaim the good news you will continue to do your work of raising others from spiritual death through the power of the Holy Spirit. Amen.
