Col. 1:26,27 – that is, the mystery which has been hidden from the past ages and generations, but has now been manifested to His saints, to whom God willed to make known what is the riches of the glory of this mystery among the Gentiles, which is Christ in you, the hope of glory.
Sometimes I think we don’t really know how much the world changed on the Day of Pentecost. Now don’t turn me off since I used that old fashioned “Pentecostal” word. Just stop and think for a minute. What was Peter’s point in that first sermon that he preached that gave birth to what we call Christianity? He said that something monumental had changed. What he said was this, all people everywhere now have access to something that is absolutely unthinkable. The Lord is pouring His Spirit on every kind of person everywhere. Young and old, rich and poor, red and yellow, black and white; no one is left out. His presence is not only on us for special empowerment, His Spirit is in us. He has become one with whosoever will. I told you it was too good to be true!!! Here is how C. S. Lewis describes this mystery.
“And this brings me to the other sense of glory—glory as brightness, splendor, luminosity. We are to shine as the sun, we are to be given the Morning Star. I think I begin to see what it means. In one way, of course, God has given us the Morning Star already: you can go and enjoy the gift on many fine mornings if you get up early enough. What more, you may ask, do we want? Ah, but we want so much more—something the books on aesthetics take little notice of. But the poets and the mythologies know all about it. We do not want merely to see beauty, though, God knows, even that is bounty enough. We want something else which can hardly be put into words—to be united with the beauty we see, to pass into it, to receive it into ourselves, to bathe in it, to become part of it.”
That is what all humans are longing for (though must don’t realize it). We want to experience the beauty of the Lord for ourselves. We want desperately to be one with Him. Sermons, songs, and prayers describe this blessing; only when you taste and see for yourself will you finally know why you are alive and what life truly is. That is the mystery that Paul preached, Christ in you the hope of glory.
