One of the many joys of being saved is realizing that Jesus didn’t just claim the allegiance of our spirit. He claimed our bodies, too!
Romans 12:1 (New Living Translation)
“And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice – the kind he will find acceptable. This is truly the way to worship him.”
1 Corinthians 6:19-20 (New Living Translation)
“Don’t you realize that your body is the temple of the Holy Spirit, who lives in you and was given to you by God? You do not belong to yourself, for God bought you with a high price. So you must honor God with your body.”
How is this a joy?
Because we realize that nothing in our life needs to be outside the realm of worship. When we exercise or eat or try to lose some weight, that can be an act of worship, an act that proceeds out of our heart of love for the Lord.
Because we love the Lord, we want to give Him our best. So, we take care of the body that belongs to Him that He has temporarily entrusted to us.
It’s not just a body, though. God dwells inside it as His temple. When we truly come to understand that principle, we will be even more motivated to give Him a place to dwell that is worthy of His presence.
Why is this important? Well, one of the reasons is because our culture is so infatuated with epithelial tissue (a.k.a. ‘skin’). Even Christians can succumb to getting their bodies slim and trim so that they can merit the attention of others. They don’t mind getting their bodies into shape so that they can impress others with how they appear. Their motive is wrong and they are stepping dangerously close to the line of temptation that has claimed so many lives (and marriages).
Take care of God’s temple today. If it needs a ‘spring cleaning,’ begin today.

But, don’t do it because you care what others will think when they see your body. Instead, do it because your body belongs to the Lord. He lives inside your body and you want to provide Him with a temple worthy of His presence.
