ANSWER: Notice (1) the end and aim of the pastor is perfection of manhood of every believer, as evinced in the ideal of which Jesus Christ is the standard. (2) By the oneness of faith and knowledge; not two unities but one, faith merging into certain knowledge (epignosis). (3) "Attain" is in the aorist tense denoting a definite point reached, not at death, but in this life as the following verses plainly show. (4) Christ is at once the source of this perfection and the standard. We find in him a sufficiency for becoming as perfect in our measure as Christ is in his. "In him are ye made full" (Col. 2:10, R. V.).
