      order--your good order; answering to "knit together" (Col 2:2) as a well-organized body; the same Greek as that for knit together, is used of the body" of the Church compacted," in Eph 4:16. Compare 1Co 14:33, 40.
      steadfastness--Greek, "the firm (or 'solid') foundation." As "order" expresses the outward aspect of the Church; so "steadfastness" expresses the inner basis on which their Church rested. The Greek literally implies not an abstract quality, but the thing in the concrete; thus their "faith" here is the solid thing which constituted the basis of their Church.
