I Corinthians 10:21-24

You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the Lord’s table and of the table of demons. Or do we provoke the Lord to jealousy? Are we stronger than He? All things are lawful for me, but not all things are helpful; all things are lawful for me, but not all things edify. Let no one seek his own, but each one the other’s well-being.
