I haven't seen the book yet, but I hope the book starts with the gospel Jesus and the disciples were preaching for the entirety of Jesus' earthly ministry before his crucifixion (3 years). There isn't two separate gospels. Can anyone comment that has read the paper copy?

Fantastic book, just what you would expect from the Keller's. Biblically based but equally important, they clearly, practically and rather thoroughly explain why the God's design for marriage works and why and where our culture, both church and secular, are failing and then they provide suggestions for the church to support both marriages and singles. Some footnotes for further reading though this is not a theology book, still this is must reading for pastors, married couples and singles all.
