When our knees start to buckle and our hands begin to feel heavy, the difficulty of the race begins to tax us. Our bodies remind us of brittle clay pots, cracking, threatening to break open as we bear the marks of difficult running. When it seems that our strength is gone, our resources diminished, our faith in jeopardy, it is then that we must remember that our sovereign God displays his grace in moments of human frailty; these are the exact times, times when we feel of little worth, that God is preparing to showcase his exceeding power in the midst of our weakness.
