God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
While it is true that people are converted and matured through expositional preaching, the word of the gospel must be wedded to the Spirit’s work in order for conviction of sin, regeneration, repentance and faith, and lifelong perseverance to come. Or to put it differently, “Neither he who plants nor he who waters is anything, but only God who gives the growth” (1 Cor. 3:7)
