Today I would like to look at 1 Corinthians 6 verse 18 to 21
18)Avoid immorality. Any other sin a man commits does not affect his body; but the man who is guilty of sexual immorality sins against his own body.
19)Don't you know that your body is the temple of the Holy Spirit, who lives in you and who was given to you by God? You do not belong to yourselves but to God;
20)He bought you for a price. So use your bodies for God's glory.
When we became Christians, we were filled by the Holy Spirit, He comes and stay within us, therefor our bodies belongs to Him. Our bodies belong to God and therefore we must use our bodies in the way God wants us to use it. We must see our bodies as God's property, He paid for it with the sacrificial death of Jesus Christ, and therefore we must use our bodies to glorify God.
I hope you have a wonderful day. May God Bless you.
Soli Deo Gloria
