3:16 dwelleth in you. See I Corinthians 6:19-20. In light of the certainty of our eventual meeting with Christ at the judgment seat, it is vital to live in daily obedience to the guidance of the indwelling Holy Spirit. We must be especially respectful of our bodies and what we do with them, for He has made them individual temples to house His glory.

3:17 destroy. This destruction must be physical death, not spiritual, for the apostle has just assured us that all in whom the Spirit dwells are eternally saved (I Corinthians 3:15). Note I Corinthians 5:5.
