Note 6 at 1 Cor. 10:22: Paul had used all these other reasonings to try and make these Corinthian "libertarians" see the light (see note 1 at 1 Cor. 10:1, p. 910). Now he gets tough. He reminds them that God is a jealous God, and He is taking a dim view of their actions.

The Lord proclaimed Himself to be a jealous God (Ex. 20:5; 34:14; Dt. 5:9). Others writing under the inspiration of the Holy Ghost proclaimed the Lord as a jealous God (Dt. 4:24; 6:15; Josh. 24:19; Ps. 78:58; Nah. 1:2). And there are recorded instances of His jealousy (Dt. 32:16, 21).

James 4:4 says, "Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God." In the very next verse (Jam. 4:5), James refers to these scriptures speaking of God as a jealous God. God takes our flirting with someone else very seriously.

Paul used all possible motivations to get these people to stop knowingly eating meat offered to idols.
