“The Spirit takes from the Scripture the grand evidence of faith which he has lodged there, and carries it to the hearts of the elect, and then the light and power of divine truth so apprehends and overcomes the soul, that it can no longer resist. That triumphant evidence is no other than the glory and excellency of the gospel scheme of salvation manifested by the Holy Spirit in such a manner as produces full conviction that a scheme so glorious could have none but God for its author. Saving faith may therefore be defined as a persuasion that Jesus is the Christ the Son of God, flowing from spiritual views of such a glory in the gospel as satisfies and convinces the mind that a scheme so glorious could have none but God for its author.“
– John Erskine, Educator and Author, 1917
