One of my students decided to practice a new spiritual discipline: Rather than gazing down at his shoes, he would look up when walking the university halls and greet others walking by. He said this was difficult for him, even at a Christian institution, as he was shy and awkward. But this discipline, he discerned, would shape him to be more like Christ and maybe touch the heart of someone in need of friendly recognition. It’s a small thing, but our spirits are shaped by small things repeated over long periods of time, and he hoped this practice would shape his character for good.
