Don't you know that you yourselves are God's temple and that God's Spirit dwells in your midst? If anyone destroys God's temple, God will destroy that person; for God's temple is sacred, and you together are that temple. (1 Corinthians 3:16-17 TNIV)
The Bible says that you yourselves are God's temple and if anyone destroys God's temple, God will destroy that person. In this case, he's not talking about you personally, but about you plural — that is, God's people, His church — and about the intentional destruction of a community of people by selfishness and gossip and fussing and just insisting on your own way.
If you have to criticize, go right to that person with the right spirit. You become a builder; you become someone who cooperates and encourages. When you care for His church — God's family — God is going to richly bless you.
