Rejoice in the Lord always; again I will say, Rejoice. Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.
In considering how to satisfy my thirst for the living water of Christ, the obvious question arises of how? God is spirit, and despite the many anthropomorphic metaphors in the Bible and the strange words of Jesus regarding eating and drinking of Him (John 6:51-58), it is not immediately clear what I actually have to do to partake of the living water that he speaks of (John 7:38). Even accepting the idea of somehow drinking of Christ, it is one thing to drink a glass of water, quite another to drink in God!
However, that phrase, ‘drink in’ provides a starting point: it is generally understood that to ‘drink in’ the sight of a beautiful sunset or the sound of uplifting music means to give yourself over to absorbing and taking in the most of the experience that you possibly can. While no finite human can ‘take in’ or absorb God in His infinite greatness, I can certainly attempt to take in the most that I can of whatever experience of Him that I can get. This is the point of the Philippians verse above — fixating my heart upon what is glorious about God (and being God, everything about Him is glorious!) is a sure way to take in who He is. And who He is is what I most need.
