Complacency is a rejection of things as they might be. "Good enough" is the motto of the complacent person. Complacency makes people fear the unknown, mistrust the untried, and abhor the new. Like water, complacent people follow the easiest course – downhill.
While our past is always there to haunt us, our salvation is accomplished in the eternal Passion of Christ. This act of God is the destination of our journey for it is here that God creates something new.
