Natural strength is what we receive from the hand of God as Creator. Spiritual strength is what we receive from God in grace.

It is not only the proclamation of the whole truth that is needed today; it is the release of the spiritual reality which the truth expresses, and that can only be realized as we allow ourselves to be caught into the mighty on-flowing tide of the Spirit.

How true it is that without the guidance of the Holy Spirit intellect not only is undependable but also extremely dangerous, because it often confuses the issue of right and wrong.

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.

Take this as the secret of Christ's life in you: His Spirit dwells in your innermost spirit. Meditate on it, believe in it, and remember it until this glorious truth produces within you a holy fear and wonderment that the Holy Spirit indeed abides in you.

If whatever men know comes through their brain without the Holy Spirit regenerating their spirit, then their knowledge will help them not one whit. If their belief rests in man's wisdom and not in God's power, they are merely excited in their soul.

Negligence in prayer withers the inner man. Nothing can be a substitute for it, not even Christian work. Many are so preoccupied with work that they allow little time for prayer. Hence they cannot cast out demons. Prayer enables us first inwardly to overcome the enemy and then outwardly to deal with him.
