1 Corinthians 3:16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
Paul begins here asking a question. As a Christian we should know that we are the house that Jesus lives in here on this earth. Remember what we covered in Galatians 2:20 “I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.” Next Paul gives us a warning that if anyone does anything to harm the body of a believer they are also doing harm to the Lord. You are attacking God, when you attack God’s servant. This should help to understand how we should treat all Christians even if they may make a mistake.
