The call of Abram is one of my favorite stories in the whole Bible. I have moved quite a lot, and the experience of packing up my life in England to move to the U.S. nearly three years ago is still fresh in my memory. The challenges that face Abram and his family are exciting, probably daunting, but certainly not without their cost. I love the way the call is vague about the destination: it seems that getting moving is more important than knowing the final details.
Once you finally get a job, then you need to get a “real” job. Then you can expect to be laid off at least once in your life. Then you have to retool and enter the workforce again. Then even if you get your “dream” job, you might come to the realization that you’re destroying your family and your personal life, and the dream becomes a bit of a nightmare. Then you begin to realign all your goals. Then you begin to look toward retirement, and you begin to imagine what your vocation is going to be when you retire.
The life of Moses is so large and significant that it's hard to imagine that we have anything in common with him—until he opens his mouth. As soon as he starts to talk he sounds just like us. When he starts offering excuses, he's not saying anything that we haven't used as reasons for not surrendering our lives to God.
