“When He, the Spirit of truth, is come,” “He will reprove the world of sin, and of righteousness, and of judgment.” [John 16:13, 8.] GW 284.1
The preaching of the word is of no avail without the presence and aid of the Holy Spirit; for this Spirit is the only effectual teacher of divine truth. Only when the truth is accompanied to the heart by the Spirit, will it quicken the conscience or transform the life. A minister may be able to present the letter of the word of God; he may be familiar with all its commands and promises; but his sowing of the gospel seed will not be successful unless this seed is quickened into life by the dew of heaven. Without the co-operation of the Spirit of God, no amount of education, no advantages, however great, can make one a channel of light. Before one book of the New Testament had been written, before one gospel sermon had been preached after Christ's ascension, the Holy Spirit came upon the praying disciples. Then the testimony of their enemies was, “Ye have filled Jerusalem with your doctrine.” [Acts 5:28.] GW 284.2
