“The god of this world has blinded the minds of the unbelieving, that they might not see the light of the Gospel of the glory of Christ, who is the image of God” (2 Cor. 4:4). Only the Holy Spirit can open our eyes. Only He can convict us of the depth of our sin, and only He can convince us of the truth of the Gospel. . . . the Holy Spirit is called “the Spirit of truth” in John 14:17.
