1 Corinthians 6:19 NKJV
Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own?
Our bodies are the temple of the Holy Spirit. We can see our bodies but we cannot see the Holy Spirit inside of us. His presence is unseen. Yet He is in us. We still have as much control as we choose to have where our bodies are concerned. The more we yield control of our bodies to the Holy Spirit, the more Jesus will be glorified in us. Yielding to the Holy Spirit is easier when we practice focusing on the unseen realm. Imagine how different our choices would be if the Holy Spirit appeared in living color before us when we were about to make a choice. He will probably not do that because God wants us to walk by faith and not by sight. We must choose to meditate on His Word and fellowship with Him more and more so that we become more Spirit-conscious than self-conscious. Then we must practice asking for His help more and listening for His responses when we need to make choices.
