1 Corinthians 10:11-12, 20-22

Now these things happened to them as an example, and they were written for our instruction, upon whom the ends of the ages have come. Therefore let him who thinks he stands take heed that he does not fall.

No, but I say that the things which the Gentiles sacrifice, they sacrifice to demons and not to God; and I do not want you to become sharers in demons. You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the table of the Lord and the table of demons. Or do we provoke the Lord to jealousy? We are not stronger than He, are we?
