-C. S. Lewis Mere Christianity
Mere Christianity is one of my favorite books. Lewis creates such wonderful ways of illustrating what it means to have faith and exercise that faith. In this section, Lewis is explaining how we become more like Christ- through practice. He likens our prayers (specifically The Lord's Prayer) and how we mimic the way Jesus addressed God...thus making us sons and daughters of God.
Lewis then goes on to describe how humorous it must seem for such flawed people to put on such a front... claiming to be children of God. However, he then draws a parallel to young children playing house: they are essentially practicing roles and what it means to be an adult- so it is as much an exercise as it is play. Sooner than you think, Lewis explains, that pretend will become reality... and our front will become more of our real being.
Today, practice being a child of God. Compose yourself as Jesus would (I know that's bordering on a cliche from the mid 90s), but maybe try to pretend a little today and maybe it will rub off on your "true" self so that you become more like Christ.
