Book excerpt: The doctrine of salvation is the watershed doctrine of Scripture. Flowing from that doctrine will be not only all other doctrine but also personal practice and Christian ministry. The major controversy concerning salvation is whether it is a result of the sovereign grace of God alone or a mixture of "God's part" and "man's part." Addressing that issue is absolutely critical to the very foundations of Christianity itself. Whichever one of those premises is correct, we should expect to find it everywhere we look in Scripture, and that is precisely what we find. There is no truth that permeates the Bible more than the doctrines of God's sovereign grace. From Genesis to Revelation, in literally hundreds of verses, these doctrines call, capture, and command our attention. Of the many books of the Bible we could choose, the Gospel of John is among the most compelling because of its foundational nature. It is there we find some of the most profound teaching on the Doctrines of Grace in all Scripture. Examining more than one hundred verses in John, this small volume presents these great biblical and historical doctrines directly from the lips of our Lord.
