In Second Peter, chapter 1, Peter reminds us that the apostles were eyewitnesses of Jesus’ majesty. But then he goes on to explain “We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place.”
In other words the prophetic Scriptures are even greater evidence of Jesus’ identity then seeing Him while He was on earth. Why? Because only God knows all of history in advance. Therefore prophecy establishes the Bible as God’s inspired Word. When sharing with non-believers, it is good to know some of the Old Testament Messianic prophecies by heart. Here are a few: In Psalm 22, written 1000 years before Christ, we are given amazing insight into the crucifixion scene of the coming Messiah. Zechariah 12:10 predicts that the Jews will look upon God whom they have pierced. Scripture also tells us that the Messiah would be a descendant of Abraham in Genesis 12:3, from the tribe of Judah in Genesis 49:10, and a descendant of King David in Isaiah 9:6-7. To confirm all these prophecies, the New Testament begins with a detailed genealogy of Jesus Christ – starting with Abraham. No other man in history has had his detailed lineage foretold centuries in advance. These and many other prophecies provide irrefutable evidence that Jesus is the promised Messiah.
When sharing, Paul reasoned from the Law and the Prophets concerning Jesus. So must we. Begin by convicted them using the Law and then confirm Christ’s identity through the Prophets.
