Of course it would be good for someone to know Christ, to love Him, and to desire with all one's heart to imitate Him to the very end. But it is not good for *me* to look at someone as though he or she is a "fixer-upper" project, like "this house would be perfect if I remodeled the kitchen and enclosed the porch to make a sunroom" (let's imagine it's a prospective marriage instead of a prospective friendship: This will be a perfect husband if I can only get him to stop smoking, drinking, playing pool with his friends, and if he would be a little more ambitious in his job and make a slightly higher salary; then he will be exactly what *I* want him to be, and of course, this also will be good for him.)
