7 by the word of truth, by the power of God, by the armor of righteousness on the right hand and on the left,
by [through] the power of God,
The gospel team had to depend on God’s power to get them through severe ministry hurdles. They did not fight spiritual wars in their strength (Ro 1:16; 1 Co 1:18; 2:4-5; 1 Th 1:5).
Paul’s team did not use rhetoric or other purely human methods for reaching people. The message of the gospel itself was mighty (1 Co 1:18). It was not necessary to use deceptive methodology geared to the emotions of men, among other things.
All ministers should lean on God’s power to work in their field of ministry.
Faith should never rest in the wisdom of men but in God’s power (1 Co 2:5). God’s power in us gets the attention of others. The proclamation of God’s Word is not merely a human activity.
