Christ in Us: by Martyn Lloyd-Jones

Dou you not know that your body is the temple of the Holy Spirit who 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 Spirit who 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.”

The Invasion: by CS Lewis

1 Peter 5:8 Be self-controlled and alert. Your enemy the devil prowls around like a roaring lion looking for someone to devour.

One of the things that surprised me when I first read the New Testament seriously was that it talked so much about a Dark Power in the universe—a mighty evil spirit who was held to be the Power behind death and disease, and sin. The difference is that Christianity thinks this Dark Power was created by God, and was good when he was created, and went wrong. Christianity agrees with Dualism that this universe is at war. But it does not think this is a war between independent powers. It thinks it is a civil war, a rebellion, and that we are living ma part of the universe occupied by the rebel.
    Enemy-occupied territory—that is what this world is. Christianity is the story of how the rightful king has landed, you might say landed in disguise, and is calling us all to take part in a great campaign of sabotage. When you go to church you are really listening--in to the secret wireless from our friends: that is why the enemy is so anxious to prevent us from going. He does it by playing on our conceit and laziness and intellectual snobbery. I know someone will ask me, ‘Do you really mean, at this time of day, to re-introduce our old friend the devil-—hoofs and horns and all?’ Well, what the time of day has to do with it I do not know. And I am not particular about the hoofs and horns. But in other respects my answer is ‘Yes, I do. I do not claim to know anything about his personal appearance. If anybody really wants to know him better I would say to that person. ‘Don’t worry. If you really want to, you will. Whether you’ll like it when you do is another question.’
