Time passed by. Pressure and hurts keep changing people's heart and tempt us to sin. Everyday we need the renewal by the Spirit and only with that we can at least keep ourselves from decay. "You are salt in the world" and people interpret that as something prevents the world from decay. In fact, very often we ourselves are in the process of decay. Jesus said, 'You can do nothing if you leave me." (John 15). How often do we remember we need to remain in him?
