CHRIST IN US
Know ye not that your body is the temple of the Holy Ghost which is in you? 1 Corinthians 6:19
The New Testament tells me that Christ is in me, and I am meant to live a life of constant fellowship and communion with Him. Sin is to look away from Him, to be interested in anything that the world can give rather than in Him. Oh, if it is something foul it is ten times worse; but the best that the world can give me is an insult to Him if I put it before Him.
There are endless statements of this. Paul puts it in terms of the Holy Spirit: “Know ye not that your body is the temple of the Holy Ghost which is in you?” (1 Corinthians 6:19). The argument is about fornication and adultery. Paul does not merely give a moral lecture on immorality; he says in effect, “What is wrong about that is that you are joining your body, which is a temple of the Holy Spirit, to another, and you have no right to do it. The way to overcome that sin is not to pray so much that you may be delivered from it; it is to realize that your body is the temple of the Holy Spirit and that you have no right to use it in that way.” Another way he puts it is this, and it is very tender: “Grieve not the Holy Spirit of God” (Ephesians 4:30). He is tender, He is sensitive, He is holy; do not grieve Him.
If you and I would only think of our lives like that, it would very soon begin to promote our sanctification. May I commend to you a simple morning rule: When you wake up, the first thing you should do (and I need to do the same) is to say to yourself, “I am a child of God. Christ is in me. That old self is gone: I died with Christ. ‘I live; yet not I, but Christ lives in me.’ Everything I do today must be in the light of this knowledge.”
