“Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own;”1 Corinthians 6:19 NIV https://1corinthians.bible/1-corinthians-6-19
Jesus walked the Earth as the perfect example of what a Christian should be. An example He showed us was when He got baptized in the Jordan. The New Testament tells us that the Holy Spirit comes to dwell within us after we are baptized.
1 Corinthians 6:19 reminds us that our bodies are like temples for the Holy Spirit. If you read the passages before, it emphasizes the importance of not violating our bodies with sin. Specifically, we should avoid sexual sin because it does not just harm our soul but our bodies as well.
