Swimmers Swim. Runners Run. Sailers Sail and Actors ... Act. Acting involves putting on the pretense (that is where "pretending" comes from) of someone else. Actors play a role. Actors go "in and out of character". Actors are able to become different people in different performances. There is a big difference between "acting" and "being". God calls us to "be" good and not merely "act" good.
Lord, help me to behave the way you desire me to behave and not merely pretend.
