As I read Psalm 119 in relation Deuteronomy 6 and Psalm 1, I meditation expanding from a reflection or prayerful study upon the Word of God to a life immersed (sitting, walking, lying, rising) in the Word of God (and in particular the 10 commandments). Meditation happens not simply in the mind/emotions but in the hands, the eyes, and the feet.
The Word moves toward incarnation. The pattern is all through Scripture. God speaks and His Word creates a world. “All things were made through Him (Logos/Word), and without Him nothing was made that was made” (John 1:3). Meditation soaks, speaks, walk, acts and even sleeps the Word. The Ten Commandments (or Ten Words) are not ideas but that takes shapes from our thoughts into our bodies. Jesus, the Word made Flesh, reveals the Law, the Commands, the Word sitting, walking, lying and rising.
One of His big complaints against the Pharisees is that they only talk about the Word, they don’t do it. “Therefore whatever they tell you to observe, that observe and do, but do not do according to their works; for they say, and do not do” (Matthew 23:3).
Meditation seems much deeper than simply reflecting, studying, praying through the Word. It seems to point to enfleshing the Word.
I'd love to hear your thoughts.
