It is not better preaching!

(J. C. Ryle)

"When the Spirit of truth comes — He will guide you into all truth." John 16:13

Does anyone of us desire to help the Church of Christ? Then let him pray for a great outpouring of the Spirit. Only the Holy Spirit can . . .
  give edge to sermons,
  and point to advice,
  and power to rebukes,
  and can cast down the high walls of sinful hearts!

It is not better preaching, and finer writing that is needed in this day — but more of the presence of the Holy Spirit!
