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.
Watchman NeePut very simply, Satan's power in the world is everywhere. Yet wherever men and women walk in the Spirit, sensitive to the anointing they have from God, that power of his just evaporates. There is a line drawn by God, a boundary where by virtue of his own very presence Satan's writ does not run. Let God but occupy all the space himself, and what room is left for the evil one?
Watchman NeeOften the children of God cannot rise up to answer the Lord's call to service simply because, though their physical condition is good, their feelings are low, cold, and reluctant. Or even when their emotions are quite high, passionate, and willing, they find themselves unable to serve the Lord because now the body reacts lazily. The disciples found themselves in precisely that situation in the Garden of Gethsemane: "the spirit indeed is willing, but the flesh is weak"
Watchman NeeLet us recognize this one thing: burden is the secret of prayer. If a person does not feel within him burden to pray for a particular matter he can hardly succeed in prayer. In a prayer meeting some brothers and sisters may mention a great many subjects for prayer. But if you are not touched inwardly, you cannot pray.
Watchman NeeWhen the fruit of your service is out of all proportion to the gifts you possess, THAT is Blessing!
Watchman NeeIn order for the inner man to be strengthened with power through the Holy Spirit, the children of God must discharge their responsibility. They need to yield specifically to the Lord, forsake every doubtful aspect in their life, be willing to obey fully God's will, and believe through prayer that He will flood their spirit with His power.
