Preparing and preaching sermons takes diligent, prayerful preparation. Therefore, ministers must devote themselves to studying, explaining and applying the Scriptures. The minister must digest the Word for himself before he feeds it to others. Puritan John Owen said unless the preacher “finds the power of it in his own heart, he cannot have any ground of confidence that it will have power in the hearts of others.”
Let’s think about it closely. What we are saying is the Holy Spirit must change a man internally before he will embrace Jesus Christ for salvation. In our sinful state, no amount of altar calls, revivals, soft piano music, or fiery preaching will persuade us to believe in Christ. You and I, alone, cannot persuade anyone to be saved. This is a work only the Spirit of God can do.
