We are united with the Lord, and by his grace made one spirit with him. Therefore, we should take special care not to sin, as our sins are really sins against the Lord, since we are one with him.
Like Joseph’s brothers, we must confess, “In truth we are guilty” (Gen 42:21). Ours may seem to us lesser or greater crimes. No matter. We are guilty.
Imagine a person who goes to church and thinks, I do not need to confess my sins because I am a good person. It is easy enough to imagine a person like this outside the church, but they exist inside the church too.
