Jesus sought out Zacchaeus and Zacchaeus was transformed into a seeker: not, of course, an indecisive and indiscriminate seeker or one who especially knows what he is seeking. Yet a real seeker whose tax grubbing hands are empty, who has not yet apprehended, but wants to apprehend because he is already apprehended (Phil 3.12f). And Jesus does not allow Zacchaeus to be merely a casual or even friendly seeker, preoccupied with unraveling facile cultural barriers. Zacchaeus is no longer a looky-loo who divides his powers between this seeking and a possessing. No! Zacchaeus is a true seeker. He seeks this one thing, his life in Christ, and all other possibilities have passed away.
And there was a man named Zacchaeus. He was a chief tax collector and was rich. And he was seeking to see who Jesus was, but on account of the crowd he could not, because he was small of stature. (Luke 19:2-3 ESV)
No one can come to Me unless the Father who sent Me draws him; (John 6.44 NASB)
For the Son of Man has come to seek and to save that which was lost. (Luke 19.10 NASB)
Like Zacchaeus, once our Seeker finds us, our lives on earth may now be defined in “seeker-only” terms. This is the meaning of the imperative (Col. 3.1f): “Seek those things which are above, where Christ sits.… Set your affection on things above, not on things on the earth.” As K. Barth puts it, “To seek that which is above means that we are to seek here and now, but not in this here and now, not on the earth, because, … the true life of the Christian is with Christ, his true and exalted life, his own proper life, which begins with the death of Christ as his own death, the death of the old man. Christ is above, and so too is the Christian in so far as he is in Christ.”
