Possessed of Christ

I would keep Your words.
I love Psalm 119. It elevates the Word of God to its rightful place in the life of a believer. Let me illustrate that with a few citations.

How can our God be our portion, our life, if we don’t delight in his Word? It is the Word of God that gives us a love for the God we worship and serve. It is His Word that gives us clarity concerning Him and His work of grace in our midst.
The Psalmist claims that God is his portion, his possession, his life. He is not
an add-on, or just another segment of his life but the totality of his life. All that he is or hopes to be is found in his love for his God as revealed in the Word of God. He has found his hope and reason for life in God apart from the circumstances of life and God’s Word has become his lamp, his food, his refuge, and his light.
For the believer, we find the culmination of this in the person of Christ, the Incarnate Word (John 1:1-3). He is the light that lights every man that comes into the world (John 1:9). All that we need to know about whom God is and how He relates to man is found in the person of Christ. Phillip found this out when he said; “Lord, show us the Father, and it is sufficient for us” (John 14:8). Our Lord’s response says it all; “Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, ‘Show us the Father’” (John 14:9)?
Those who seem to have tired of Christ have neglected the revelation of Christ in the Word of God. They have not seen the majesty, the immenseness of the person of Christ simply because the have not allowed the Holy Spirit through the Word of God to bring them into captivity to Christ (cf. 2 Corinthians 10:4-5). His beauty, His grace, His holiness, and His majesty have been missed simply because many have neglected the Word of God.
I suppose the question is not so much that His Word is our portion or possession but rather has Christ, through the Word, possessed us? That will happen when the Word of God possesses us!
