The Bible is not enough
Hotels and motels in America used to share one thing in common: A Bible from the Gideons. If you consider why people go to a motel, you’ll begin to understand why the Bibles are there, too.
Of course, I think this is a good thing. But, is it enough?
Even Jesus didn’t think so:
“And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself” -Luke 24:27
What’s the point? Jesus needed to point out (to His own disciples, nonetheless) that the trajectory of the Old Testament was Himself, Jesus of Nazareth.
John 5:39 states:
“You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me …”
Even Jesus’ disciples interpreted the Old Testament through the lens of Jesus, from Acts 8:
This means that the individual who doesn’t understand scripture needs a teacher to interpret it Christologically for them. It is the most critical part of evangelism. Christians who view the Scripture as mainly about something other than Jesus Christ are not capable of seeing a conversion like the Ethiopian Eunuch’s.
This is a good one-page article by Horace Hummel on understanding the Old Testament Christologically: http://www.mtio.com/articles/aissar5.htm
May God lead us into opportunities to do just this.
