The one who fulfills the work of pastoral ministry as he ought stirs up and fans this gift. The one who does not fulfill it quenches it. The same happens here as with those who received talents in the parable: one puts the talent he received into circulation, another buries it in the ground.
Both figurative expressions mean one and the same thing. It is not enough to receive the gift of grace. One must also stir it up, or develop it, by laboring in the work for which it was given.
The Apostle expressed this with the word αναζωπυρειν, to fan, to give sufficient ventilation, or movement of air, so that the fire does not go out but burns more and more. What the movement of air is for fire, labors according to the gift of grace are for that gift.
This is what the Apostle reminds Saint Timothy of when he says: “For this reason I remind you to stir up the gift of God.” But for what reason? For the sake of the faith which lives in him and in his family. This faith obliges him to stir up the gift of God.
The gift was given according to faith and received by faith. Yet faith also presents the strongest motives for zealous action according to the gift. The Apostle says, as it were: after I have enlivened faith in you by the preceding remembrances, I have no need to persuade you at length. It is enough simply to remind you to stir up your gift.
But here one may also understand this: since you believe sincerely, by that very fact labor more zealously in stirring up your gift. See that you do not grow negligent. With faith, failing to stir up the gift is an inconceivable inconsistency.
Saint Chrysostom says: “I know that you have unfeigned faith, and therefore I remind you: one must have zeal in order to stir up the gift of God. As fire requires wood, so grace requires our zeal, that it may be kindled. The gift of God means the grace of the Spirit, which you received for presiding in the Church, for signs, and for every ministry. Stir it up, for it depends on us both to quench and to kindle it. Therefore elsewhere he also says: ‘Do not quench the Spirit’ (1 Thess 5:19). From carelessness and laziness it is quenched. From attention and zeal it is kindled.”
