When preaching is faithful to the Scripture, James P. Boyce, founder of The Southern Baptist Theological Seminary declared:
“It is not man only that tells of sin and offers a Savior; not man only that presents promises of acceptance through Christ; not man only that calls his fellows to repentance and trust in Jesus; not man only, that invites to a life of full consecration to God, and gives assurances to help in the attempt to lead that life.” Faithful preaching constitutes “the voice of God—of the living God. It is the invitation of Christ—the ever-present Christ. It is the Holy Ghost whose sword is thus unsheathed to convict of sin, of righteousness and of a judgment to come.”
