1 Corinthians 6:19-20

You should know your body is a temple for the Holy Spirit who is in you. You have received the Holy Spirit from God. So you do not belong to yourselves, because you were bought by God for a price. So honor God with your bodies.

2 Corinthians 5:17 says...

If anyone belongs to Christ, there is a new creation. The old things have gone; everything is made new!
