True familiarity with Christ inevitably transforms us into his likeness. Thus, to say that we know Christ without reflecting his likeness (even if not yet perfectly) is a contradiction in terms. Worship, prayer, and a life lived in conscious awareness of his presence are the usual contexts for this transformation. Nevertheless, it is quite possible to be immersed in a life of worship and prayer while possessing a heart fundamentally closed to transformation because of the cost involved. It is therefore instructive that those knocking at the already locked door speak of eating in his company which, I think, is somewhat different from the intimacy involved in actually sharing a meal with him—and being transformed by the experience. We have thus to be on the watch for merely going through the motions of worship and prayer while our hearts are closed, or distracted, or simply disengaged from what we are doing externally. Otherwise we will bear no resemblance to the one we worship and he will not recognize us when we knock and seek entry into the eternal kingdom.
