Just hadn't been discovered. Through discovery, things become knew to us, we discover something that was there all along. Had to discover where the bathroom was. It didn't just appear when we got there, its been there all along. When you are Christian, want to discover more about Christ and about being a Christian.
Discovery is a life long process.
Learn to grow as Christians and become better friends with Jesus. There is a story in the bible about two men in Luke 24. The crucifixion of Christ. All of a sudden, a man started walking with them, and talking with them. He asked them what they were discussing, and they were amazed that He did not know about all the things that had been happening.
