If Jesus is present in us, we go out of our way to help others, we learn to forgive, we become loving, etc. But sometimes, we fail to be sacraments of Jesus because of sin. When we are selfish, greedy, jealous, unforgiving, and others, we do not allow Jesus light to shine through us. To be a kind of sacrament is to be a symbol that others can see, respect, and admire.
