Fight the good fight of faith,.... The apostle suggests to Timothy, that he had other business to do than to mind the things of this world; his life was a state of warfare; he was a soldier, and was not to entangle himself with the things of this life; he had many enemies to engage with, as Satan, and his principalities and powers; sin, and the lusts of the flesh; the world, and the men of it, and a great fight of afflictions to endure with them; as also false teachers, with, whom particularly he was to fight the good fight of faith, that so the truth of the Gospel, which they resisted, might continue with the saints.
This fight is called "the fight of faith"; partly in opposition to the law, and to hrwt lv htmxlm, "the fight", or "war of the law" the Jews so much talk of; and in which the false teachers, in the apostle's time, were so much engaged, and against whom the apostles set themselves; and partly because the doctrine of faith, the faith of the Gospel, the faith once delivered to the saints, is what they earnestly contended, strove, and fought for; and because the grace of faith, as conversant with the Scriptures of truth, was the weapon they fought with: and this may be called a "good fight", because it is in a good cause, the cause of God and truth; and under a good Captain, Jesus Christ the Captain of our salvation; for which good weapons are provided, even the whole armour of God, and which are not carnal, but spiritual and mighty; to which may be added, that those who are engaged in this fight may be sure of victory, and the crown of glory, life, and righteousness: so that when they have done fighting they have nothing else to do but tolay hold on eternal life; as Timothy for his encouragement is here bid to do.
Eternal life is the prize of the high calling of God, which is held up, and held forth to those who are fighting the Lord's battles; and this they should look unto as the recompense of reward; and this they may lay hold upon, even now by faith, believing their interest in it, their right unto it, and that they shall enjoy it; of which they may be the more assured, because of their effectual calling:whereunto thou art also called; not barely by the external ministration of the Gospel, in which sense many are called, but few chosen and saved; but internally, by the special grace and power of the Spirit of God; and such who are so called, are not only called to grace, but to eternal glory; and the God of all grace, who has called unto it, of his sovereign good will and pleasure, is faithful, and will bestow it.
The word "also" is left out in the Alexandrian copy, and in the Vulgate Latin, and in all the Oriental versions; but it seems to be emphatic, and is used to strengthen Timothy's faith, as to the enjoyment of eternal life; since it was not only the reward of grace, following upon the good fight of faith, but was that also to which he was called by the grace of God:and hast professed a good profession before many witnesses; both before the brethren at Lystra, at his baptism and admission into the church, before whom he gave an account of his faith, and made a profession of it; and who, upon this, and his agreeable life and conversation, gave a good report of him to the Apostle Paul, Ac 16:1 and before the apostle, and the rest of the elders, when they laid their hands on him, whereby an extraordinary gift was conveyed unto him, 1Ti 4:14 or it may be before the men of the world, some violent persecutors, before whom he bravely, and with great intrepidity, professed his faith in Christ Jesus; and which he continued constantly to do, in every place wherever he came; and which being done so often, and so publicly, is a reason why he should keep on till the battle was over.
