As Christians, we each should strive to be the likeness of Christ. But we each are a part of The Body of Christ, which is The Church. What each one does affects the whole Body of The Church. It’s not easy to comprehend, because as individuals we tend to only think of our own concerns, and consequences. 
God help us to remember to always confess sins, and seek forgiveness for our benefit, and that of the Body of Christ, The Church.
