The Bible tells us God knew us before we were born, that he called us by name and has a great plan for each of our lives. The amazing thing about it is that he already went ahead of us and worked out all the details. We are not in charge of figuring everything out. We are not responsible for qualifying ourselves. God qualifies us  therefore our qualifications aren't based on the worlds standards. Our "lack" doesn't determine our ability to walk in the calling God has for us. "In our weakness, his power is made perfect".
