[Luke]

1Co 3:16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
1Co 3:17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.

Are these verses referring to the individual believers body as the temple of God, or the church (invisible) as the temple of God?

Whichever one it is, what do these verses mean for someone who has defiled the temple of God after salvation?
