I always point to the Lord's preaching the gospel entirely from the Old Testament on the road to Emmaus. In that exchange, we are told the He told His disciples "from Moses and the prophets, all the Scripture said concerning Himself."

Imagine preaching the gospel entirely from the Old Testament! I know of very few who do that today, but Jesus and the Apostles preached the gospel entirely from the Old Testament. The fact of the single thread of Christ's work, prefigured in all the law and the prophets, proves Dispensationalism wrong. The bible, from beginning to end, is a book about Jesus!

That, and of course, Ephesians chapter two, which I think all by itself destroys Dispensationalism by describing the Lord's work in having "made the two (Jew and Gentile) into one," and Paul's emphasis that the children of Abraham are not descendants by geneaolgy but by FAITH.
