“It is the preacher’s business to show wherein spiritual inability consists: not in the lack of soul faculties, but in the absence of any love for Him who is infinitely lovely. Far be it from us to extenuate the wicked unbelief of the unregenerate.”
“When Peter said, ‘Repent ye therefore, and be converted, that your sins may be blotted out’ (Acts 3:19), He that is exalted to give repentance to Israel and forgiveness of sins, sent His Spirit and Grace with the Word to work repentance and conversion in His own elect. And though they spoke the Word, promiscuously to all, yet He only spake it to His own. It was sent with the power of the Spirit. It never was sent with the Spirit of Faith to any but His own: ‘When the Gentiles heard this, they were glad, and glorified the Word of the Lord: and as many as were ordained to eternal life believed’ (Acts 13:48)”.
