[Your spiritual food] must be continually sought. Do not try to live on last year’s manna. Stale experiences are poor food… [Y]ou need to have a daily realisation of the things of God.
[B]e not idlers with the Word of God–search it. Get up early in the morning to read your Bible if you cannot do it at others times. Steal from your sleep a happy hour to read the Scriptures. Diligently and earnestly seek the Lord, for He has said, “They that seek Me early shall find Me.”
