1 CORINTHIANS 6:19!! SPREAD THE WORD!
If you are a Christian, then the Holy Spirit of the Most High God lives inside of you!
Paul shows us in 1 Corinthians 6:19 that this clearly should effect the way we treat our bodies, now that they are responsible for carrying the Gospel to this world.
We should not take care of our bodies for our own good, staying physically fit and sexually pure, but also out of love for your Saviour, Jesus, who laid down His life for us.
