Christ liveth in me

What a great old song is "Christ Liveth in Me" by Daniel Whittle. Especially wonderful is the last verse; 
With longing all my heart is filled,
That like Him I may be,
As on the wondrous thought I dwell
That Christ liveth in me.

The wonder of that thought leads my mind to think "how can this be?" Well good for Paul, he spells it out for us in 2 Corinthians 3:18. And in the mist of this verse he uses a Greek participle that in its tense and mood tells us how this all happens. The key word is katoptrizomenoi. Yes I know it is an eye full and when you say it, it is a mouthful. But it is does mean what Paul wants it to mean. According to R. Mounce, the present adverbial participle has a continuous action to it. The root word has developed over time from "gazing in a mirror" to "contemplation". It has a further addition of the noun ending which when used as an instrument can mean "by contemplating". So if we put this verse together we see that it says "We all are being changed into the image of Christ by contemplating on the glory of the Lord." This is the key. We continually contemplate, reflect on the lord and the change happens. Another important word in this verse is  "change".  In Greek it is metamorphoumetha, yes that's right "metamorphosis". As we continually behold the Lord we metamorphize into him. Gradually our thoughts, our hearts and our spirits are changed from glory to glory, by the spirit. But the emphasis for me  is the continuous contemplation of him. I don't change because of my deeds, though wonderful, or my actions though righteous : ), but through beholding Him.  Christ becomes alive and more alive and more alive in me. Salvation has come to me. I don't work to become it, except by reflecting upon Him. "Oh what a salvation this, that Christ liveth in me."
