New Testament themes found
in the Old Testament
The concepts in the New Testament were not derived out of thin air. Amos 3:7 says, "Surely the Lord God does nothing unless He reveals His secret counsel to His servants the prophets." What is mentioned in the New Testament is revealed in the Old Testament either clearly or in types and figures. Gen. 22 is a great example of the sacrifice of Jesus, the Son in Typology represented by the sacrifice of Isaac.
Following is a chart that exemplifies many of the themes that were revealed in the Old Testament and fulfilled in the New. It is easy to see that there is no need at all for the Christians to borrow from any source outside the Old Testament.
John 5:39, "You search the Scriptures, because you think that in them you have eternal life; and it is these that bear witness of Me."
