All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
All Commentaries on 2 Timothy 3:16 Go To 2 Timothy 3
John Chrysostom
AD 407
Having offered much exhortation and consolation from other sources, he adds that which is more perfect, derived from the Scriptures; and he is reasonably full in offering consolation, because he has a great and sad thing to say. For if Elisha, who was with his master to his last breath, when he saw him departing as it were in death, rent his garments for grief, what think you must this disciple suffer, so loving and so beloved, upon hearing that his master was about to die, and that he could not enjoy his company when he was near his death, which is above all things apt to be distressing? For we are less grateful for the past time, when we have been deprived of the more recent intercourse of those who are departed. For this reason when he had previously offered much consolation, he then discourses concerning his own death: and this in no ordinary way, but in words adapted to comfort him and fill him with joy; so as to have it considered as a sacrifice rather than a death; a migration, as in fact it was, and a removal to a better state. For I am now ready to be offered up 2 Timothy 4:6, he says. For this reason he writes: All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness. All what Scripture? All that sacred writing, he means, of which I was speaking. This is said of what he was discoursing of; about which he said, From a child you have known the holy Scriptures. All such, then, is given by inspiration of God; therefore, he means, do not doubt; and it is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, thoroughly furnished unto all good works.
For doctrine. For thence we shall know, whether we ought to learn or to be ignorant of anything. And thence we may disprove what is false, thence we may be corrected and brought to a right mind, may be comforted and consoled, and if anything is deficient, we may have it added to us.
