'Meditation is looking at the Word of God like a thirsty tree looks at water. This shows us that meditation goes beyond the intellectual. It is spiritually "tasting" Scripture - delighting in it, sensing its sweetness, thanking and praising God for what you see. It is also spiritually "digesting" Scripture - applying it, thinking about how it affects you, describes you, and guides you in the most practical way. It is also drawing strength from the Scripture - letting it give you hope, using it to remember how loved you are.'
Timothy Keller, Prayer: The Leader's Guide, p.70.
