Thomas Merton

If we can, by God’s grace, turn ourselves entirely to Him, and put aside everything else in order to speak with Him and worship Him, this does not mean that we can always imagine Him or feel His presence. Neither imagination nor feeling are required for a full conversion of our whole being to God. Nor is intense concentration on an idea of God especially desirable. Hard as it is to convey in human language, there is a very real and very recognizable (but almost entirely undefinable) Presence of God, in which we confront Him in prayer knowing Him by Whom we are known, aware of Him Who is aware of us, loving Him by Whom we know ourselves to be loved.
