How is it exactly that God’s way our higher than our ways? (Isaiah 55:9)
[The religious leaders, as well as Jesus’ own disciples asked him many questions.] As was so often the case, Jesus didn’t answer their questions directly. Many of the questions we ask God can’t be answered directly, not because God doesn’t know the answers but because our questions don’t make sense. As C.S. Lewis once pointed out, many of our questions are, from God’s point of view, rather like someone asking, “Is yellow square or round?” or “How many hours are there in a mile?” Jesus gently puts off the question. “It isn’t for you,” he says, “to know the times and periods which the Father has set by his own authority. But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth”.
