The particular sin of omission which gives ground to the evil spirits is the believer’s passivity.

To walk after the spirit a believer must inhibit his mind from revolving endlessly. If it turns too long around one topic, worries or grieves too much over matters, and ponders too intensively to know God's will, it may become unbearable and hamper its normal operation. The mind needs to be kept in a steady and secure state.

A mistaken thought may be corrected easily, but an errant affection is nearly unmanageable.

True revelation of the fact of the Spirit's indwelling will revolutionize the life of any Christian.

Since this life is God's and cannot die, it follows that everyone born anew into possessing this life is said to have eternal life.

To remove warfare from a spiritual life is to render it unspiritual. Life in the spirit is a suffering way, filled with watching and laboring, burdened by weariness and trial, punctuated by heartbreak and conflict. It is a life utterly outpoured for the kingdom of God and lived in complete disregard for one's personal happiness.

Faith in Christ makes one a regenerated believer; obedience to the Holy Spirit makes him a spiritual believer.
