You can be like Abraham. In fact, you're probably a lot like him already. He has his ups and downs, too. He would have moments of greatness then fall flat on his face. His humanity kept getting in the way. God's call and instructions were clear, but Abraham frequently wondered if he could pull it off. He was sometimes a confused and uncertain as the rest of us.
Yet, In spite of his human failings, Abraham was the founder and leader of God's chosen people. He is identified in the Hebrews as a hero of the faith, and God called Abraham His friend.
So what made the difference in Abraham's life? The secret to his greatness was that he learned how to walk with For in total faith and obedience. And That's a lesson we cam all take from Abraham.
