Since the Holy Spirit authored the Word of God, He knows that Word better than anyone. The Holy Scriptures were given to us by the Holy Spirit to help us build up our inner man and give us access to the power and presence of God. If we want to train our human spirit, the place to begin is to yield to the Holy Spirit and allow Him to lead us to what passages to read and meditate upon. God does the work, but we have a part to play. Developing a strong human spirit requires reading and digesting the scriptures. We can only digest the Word of God by meditating on it. Just as we can best digest our natural food if we chew it well, meditating on the Word of God helps us digest what we read. Meditating is the same as chewing; it gives the digestion process a head start.
