Receiving the Holy Eucharist is not a casual affair. In 1 Corinthians 11:27, Paul wrote that "whoever eats the bread or drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord." Before we receive the Sacrament, we should make sure that we are in as pure a state as possible spiritually. Then we ask the Lord to bestow on us whatever we need to be drawn close to him. We must become more like him, even for a tiny bit, after each reception.
