1 Corinthians 6:19

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?

When we were born again, we became a temple for the Holy Spirit.  We are never alone.  God is in us and with us wherever we go.  God sees everything we see and goes with us everywhere we go.  A temple is a place that should be honored and kept as holy.  God wants us to be aware we were bought with a price and have a high value to Him.
