“We turn each truth that we learn about God into matter for meditation before God, leading to prayer and praise to God.
Meditation is the activity of calling to mind, and thinking over, and dwelling on, and applying to oneself, the various things that one knows about the works and ways and purposes and promises of God.
Its purpose is to clear one’s mental and spiritual vision of God, and to let His truth make its full and proper impact on one’s mind and heart.
It is a matter of talking to oneself about God and oneself: it is, indeed, often a matter of arguing with oneself, reasoning oneself out of moods of doubt and unbelief into a clear apprehension of God’s power and grace.”
