From time to time, skeptics have attempted to do exactly what you suggest — and the result has always been a failure. All they had left was a vague and confusing mass of material with little unity or coherence.
The reason is because the only way to remove the miracles from the Bible is to remove God from the Bible — because He is the One who caused the miracles to happen. And yet His footprints are on every page — and without God, the Bible falls apart. From the very first verses of Genesis to the final chapter of Revelation, the Bible is the story of God and His plan for the human race. As the Bible says, “‘I am the Alpha and the Omega,’ says the Lord God, ‘who is, and who was, and who is to come, the Almighty'” (Revelation 1:8).
The Bible’s miracles are an important part of its story, and it is impossible to extract them from the Bible without destroying its central message. What is that message? It is the message that God is real, and He created us so we could know and love Him.
But the Bible also points us to the greatest miracle of all — the miracle of Jesus Christ. He came from heaven to demonstrate God’s love for us, and He did this by dying for us. Don’t turn your back on Christ, but ask God to help you understand how much He loves you — and then to commit your life to Him.
