Word and Spirit
The progress from a changed consciousness to a changed conviction is directed by the Holy Spirit. The Spirit works with the Word. He does not work against the Word or without the Word. The Word and the Spirit go toge!her. Doctrine and life go together. To separate them is to frustrate the work of sanctification within us and to grieve the Holy Spirit.
-R. C Sproul
Preaching has no power unless God the Holy Spirit takes His Word and penetrates hearts with it.
"You do not know who the elect are. You do not know whose heart will be broken by the divine hammer of truth. But it is your responsibility to use the divine hammer on the hard heart. And as the gospel is preached it will attract to itself, by its own power, through the Holy Spirit, those whom God has ordained unto eternal life."
- C. H. Spurgeon
"For we know, brothers loved by God, that he has chosen you, because our gospel came to you not only in word, but also in power and in the Holy Spirit" 1 Thes 1:4, 5
