While we can't always affect the configuration of our body (our exterior world), I think we can always custom-design the interior world of our souls. The DNA is there. What we take up and live out is our responsibility and opportunity to give back to God what was His idea in the first place. We are created in His image to bless the earth and those in it. A soul's force reaches beyond sight, touch, sound, and smell to a reality that lasts forever, flows forward and backward, and has infinite opportunities to draw nearer to God—through the people we know and get to know, the places we've been and plan to go, and every choice we make along the way.
