Word and Spirit in Conversion

"We must never divorce what God has married, namely his Word and his Spirit. The Word of God is the Spirit's sword. The Spirit without the Word is weaponless; the Word without the Spirit is powerless." (The Message of Thessalonians pg. 34)

Preach the necessity for the Holy Ghost’s divine operations. ... ‘Men must be told that they are dead, and that only the Holy Spirit can quicken them; that the Spirit works according to his own good pleasure, and that no man can claim his visitations or deserve his aid. This is thought to be very discouraging teaching, and so it is, but men need to be discouraged when they are seeking salvation in a wrong manner. To put them out of conceit of their own abilities is a great help toward bringing them to look out of self to another, even the Lord Jesus. The doctrine of election and other great truths which declare salvation to be all of grace, and to be, not the right of the creature, but the gift of the Sovereign Lord, are all calculated to hide pride from man, and so prepare him to receive the mercy of God.’
