Communion is not a good luck charm, nor is it a substitute for the other valuable disciplines of a believer’s life. It is also not to be trifled with. Bitterness, sexual perversion, and other unconfessed sins can create severe issues, including illness. It is an act of power. Done correctly, we should believe that it aligns us with God’s purposes and fills us with His power. Done flippantly, we should be concerned about the effects of “playing with the power of God.”
