“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...It is an activity of holy thought, consciously performed in the presence of God, under the eye of God, by the help of God, as a means of communion with God.” (Packer, J I: Knowing God)
"To meditate in God’s word is to discourse (discuss with God in prayer) concerning the great things contained in it, with a close application of mind, a fixedness of thought, till we be suitably affected with those things and experience the savour and power of them in our hearts."...
"Meditation is screwing the truth of God into our hearts until it catches fire." --Tim Keller
