Walter C. Kaiser Jr. (Wikipedia profile; his personal web page) is a Bible scholar who brings to light how much the Bible talks about Christ (though Kaiser more commonly uses the Hebraic term Messiah, Christ being the Hellenistic version). His book, The Messiah in the Old Testament, is an example of this.
Kaiser talks about “the promise-plan” of God in which he sees Messiah (i.e. Christ) occupying the central personal role. This kind of focus reveals how Jesus is the Bible’s common thread and constant preoccupation.
So many people read the Bible without an appreciation of the fact that it’s all about Jesus Christ – Old Testament included (John 5:39; Luke 24:25-27, 31-32, 44-48; 2 Timothy 3:14-15). Kaiser’s writings can help put such people on the right track.
I should add, however, that there is much more to see about Christ in the Bible than even what Kaiser puts forth.
