By the word of truth
By preaching the Gospel, truly, sincerely, without any adulteration of it, which comes from the God of truth, has for its subject matter Christ, who is the truth, and into which ministers are guided by the Spirit of truth, and every doctrine of which is truth:
by the power of God;
accompanying the word to the conversion and salvation of multitudes of souls; or by the signs, wonders, and miracles which were wrought for the confirmation of it:
by the armour of righteousness, on the right hand, and on
meaning, either the whole armour of God, with which a Christian is all over clothed from head to foot, and in the strength of Christ may engage any adversary without fear; or else particularly the sword of the Spirit in the right hand, and the shield of faith in the left, whereby both the offensive and defensive part may be acted; or, as others think, uprightness of conscience, and holiness of life and conversation; with which being blessed, though on the one hand he meets with prosperity, and on the other hand with adversity, he is not lifted up with the one, nor cast down with the other; he is moved by neither, but passes on unconcerned.
