[Do you not know] that Jesus Christ is in you? - Paul exhorts these same Corinthians:
And what agreement has the temple of God with idols? For you are the temple of the living God. As God has said: "I will dwell in them and walk among them. I will be their God, and they shall be My people." Therefore "Come out from among them and be separate, says the Lord. Do not touch what is unclean, and I will receive you." "I will be a Father to you, and you shall be My sons and daughters, says the Lord Almighty." Therefore, having these promises, beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God. (II Corinthians 6:16—7:1)
Because we are God's children, we are special, but nothing of our own makes us special. It is only God dwelling in us by His Spirit that separates us from others. But what a difference that makes!
Jesus says in John 14:23, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him." This should make us think, "What kind of home am I providing for the Sovereign God and His glorified Son?" Our desire to give God nothing to judge as unworthy of His presence should run the gamut from our physical health to our most secret thoughts.
Clearly, every one of us falls short. But this is why Paul exhorts us to cleanse ourselves, continually maturing in holiness in the fear of God. We are to scrub deeply out of deep reverence for Him who dwells in us.
