Matthew Poole and continuators on 2 Timothy 1:14

14 That good thing which was committed to thee , keep by the holy Ghost which dwelleth in us .

This is expounded by 1 Tim. 6.20. he means the Doctrine of the Gospel, or his Office in the publication of it, be faithful in thy ministerial work;

To which purpose beg the assistance and operation of the Holy Spirit, which dwelleth both in all believers, and more particularly assisteth the Ministers of the Gospel; we can neither keep our minds sound in the Faith, as to the Doctrine of it, nor our Souls steady in the exercises of Faith, or Love without the assistance of the Holy Spirit, which yet the Lord giveth to them that ask him, and it abides in them, who do not vex, quench, grieve, and resist it.
