Reflecting on Abraham

I can't help but reflect on today's 1st reading Genesis 22:1b-19. "God put Abraham to the test." Anyone who reads the bible or listens at mass knows Abraham is asked to offer his only son. I want so badly to follow in the footsteps of Abraham. Many times God has led me into a fear filled situation. I try with all my being to follow His will. My struggle is that as soon as I do it, I start to doubt. I know in my head, doubt doesn't come from the Lord. Please Jesus from this moment, I hand my whole life over to you. I can't give you half of my heart. Take it all. Leave me with noting, because unless you hold my whole heart I will always worry that I may want something left for myself. But, if I give it all to you, I will have nothing to lose. I am yours Lord, I am yours, do with me as you will.
