Exodus 10-1 says, And the Lord said unto Moses, Go in unto Pharaoh, for I have hardened his heart and the heart of his servants, that I might show these my signs before him. God, in this Old Testament appearance of Jesus, referred to as a theophany, confirmed Moses as leader of Israel by signs, and we see that in Exodus 4 to begin with. Then the Lord set Israel apart from Egypt, which is a type of the world, with the sign of the plague of swarms of flies. That's in Exodus chapter 8. And he said to Pharaoh in Exodus 8.23, And I will put a division between my people and thy people. Tomorrow shall this sign be." Then we come to our text in Exodus 10.1, where Jesus is talking to Moses and tells him that after Pharaoh hardened his heart in rebellion against God, the Lord would now use that and further harden Pharaoh's heart for the purpose of releasing the final three signs of plagues, beginning with the plague of locusts. Then the Lord tells Moses the purpose of these signs as it relates to Israel in the next verse, Exodus 10, 2, where he said, and that thou mayest tell in the ears of thy son and of thy son's son, what things I have wrought in Egypt and my signs, which I have done among them, that ye may know how that I am the Lord. There is no other nation, and no, not even the Church, in which the Lord proves himself by signs. Only Israel is told to look for signs, as the Apostle Paul confirms in 1 Corinthians 1.22, which says, For the Jews require a sign, and the Greeks seek after wisdom. The Jews require a sign because Jesus established his signs as required confirmation with the Jews. The modern charismatic movement has it all wrong when they claim that the so-called signs and wonders movement would usher in some sort of global revival or really any legit revival of any sort. Signs are for the Jew because the Messiah of Israel, Jesus of Nazareth, is God of signs and wonders. Sadly, the Jews themselves rejected the confirmation of Jesus as Messiah, as we see in Matthew, Mark, Luke, and John. Not only his fulfillment of Bible prophecy, but the signs he performed right before their eyes, as Peter said when confronting them at Pentecost. in Acts 2.22 saying, Ye men of Israel, hear these words. Jesus of Nazareth, a man approved of God among you, by miracles and wonders and signs which God did by him in the midst of you, as ye yourselves also know. And there are dozens of other examples of Jesus pre-incarnate and Jesus incarnate confirming his word and his claims by signs. But even after he ascended to heaven and sent his Holy Spirit, who confirmed the resurrection of Jesus by many signs and wonders, beginning with the sign of tongues of Pentecost, and it's all recounted throughout the book of Acts, the Jews persisted in their unbelief as a nation and as a mass majority individually. Hebrews 2 refers to this saying, God also bearing them witness, the apostles. both with signs and wonders, and with diverse miracles and gifts of the Holy Ghost, according to his own will. Paul confirmed this again in 2 Corinthians 12.12, where he wrote that, truly, the signs of an apostle were wrought among you in all patience, in signs and wonders and mighty deeds. The Bible is now complete. The sign Jesus has left us and left the whole world, including Jew and Gentile, since the completion of the Bible is his death, burial, and resurrection. And Jesus referred to this in Matthew 12, 39, 40. But he answered and said unto them, an evil and adulterous generation seeketh after a sign. He said that after he'd already demonstrated beyond reasonable doubt with all kinds of signs. And then he goes on and says, and there shall no sign be given to it. but the sign of the prophet Jonas. For as Jonas was three days and three nights in the whale's belly, so shall the Son of Man be three days and three nights in the heart of the whole earth. When we repent toward God with faith toward the Lord Jesus Christ, confessing with our mouth and believing with our heart that God hath raised him from the dead, then we're told in Romans 10, 9 and 10, we are saved. Jesus is God of signs and wonders, and his own bodily resurrection iced the cake.
