"That the man of God may be perfect, throughly furnished unto all good works." 2 Timothy 3:17

What perfection does the Holy Spirit speak of here? Certainly not perfection in the flesh; that is but a wild dream of free-will and Arminianism. But perfection here and elsewhere means a being well-established and grounded in the faith, as we find the Apostle speaking (Heb. 5:14), "Strong food belongs to those who are of full age" (literally, as we read in the margin, "perfect"), "even those who by reason of use have their senses exercised to discern both good and evil." Christian perfection does not then consist in perfection in the flesh, but in having arrived at maturity in the divine life, in being what I may call a Christian adult, or what the Apostle terms "a MAN in Christ."

When Paul therefore says, "Let us therefore, as many as be perfect," he means "being no more children, tossed to and fro, and carried about with every wind of doctrine," but favored with a measure of Christian wisdom and strength. It is this Christian maturity which is called in Scripture, "perfection," and it is only obtained by suffering. It is only in the furnace that the tin and dross of pharisaic righteousness is purged away; and the soul comes out of the furnace "a vessel unto honor, sanctified and fit for the Master's use."
