This is the wrath that will be revealed at the dread judgment. The Apostle keeps our thought fixed on that decisive moment.
Above he did this with the words, “you will appear in glory.” Here he does it with the words, “the wrath of God is coming.”
He teaches that whoever will not put his passions to death will not only fail to appear in glory, but on the contrary will meet the wrath of God. Then comes the final reckoning.
Even now the wrath of God comes, but now it is temporal and corrective. Then it will be decisive and irrevocable.
Here the Apostle has the same thought as in Romans: “The wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness” (cf. Rom 1:18).
By sons of disobedience the Apostle means unbelievers, both Jews and Gentiles, who seeing do not see and hearing do not hear. Whatever one says to them, and however one persuades them, nothing takes hold of them.
A sound preaching is offered, and they do not heed it. Signs are added to the word, and even this does not persuade them. They are like a stone which no instrument can work.
Therefore they are called sons of disobedience, απειθειας, of being unpersuaded. It is as though their nature were to be persuaded by nothing and to desire no persuasion.
Blessed Theophylact writes: “He calls them sons of disobedience, depriving them of every excuse and showing that they remain in the passions not through ignorance, but through stubbornness, εξ απειθειας.
They have so given themselves over to it that they have, as it were, adopted themselves to it, receiving from it their distinguishing and characteristic features.”
Something fearful is brought upon such people by the Savior’s words. They do not listen because they are not of the truth. For “everyone who is of the truth hears My voice” (Jn 18:37), says the Lord.
They are not of the truth, and there is no truth in them, as there is none in him who was a murderer from the beginning (Jn 8:44). There is no truth in them.
Truth is not received by them. It does not fit within them, finding nothing akin to itself in them. The truth of God walks on the earth and has faithful witnesses to itself.
Whoever sincerely desires it will always find it. If there are those who do not find it, it is because they do not seek it. They do not seek because they do not want the truth.
They do not want it because they are not of the truth. Yet there is nothing fatalistic in this. Everything is the work of free will.
By reminding the Colossians of the coming wrath, the Apostle offers an incentive for the mortification of the passions. The remembrance of God’s benefits is sufficient to restrain one from passions and sins.
But the presentation of God’s wrath is stronger than all for this purpose (see Chrysostom). “The Apostle considered it necessary to add the threat of punishment to his persuasions” (Blessed Theodoret).
Why so? Perhaps because of the nature of the passions from which he prescribed withdrawal and which he commanded to be mortified.
The passion of lust and covetousness respond poorly to the action of remembering God’s benefits. While these passions are not in motion, that remembrance has its effect.
But when they stir, nothing sobers so powerfully as a living representation of the coming wrath of God. In general, to stand attentively at the judgment is the best place for an ascetic.
It is an especially useful place when the passion of lust is in motion.
