Isaiah speaks again a message from God about what he sees concerning Judah and Jerusalem specifically. “In the last days, the mountain of the Lord’s house will be the highest of all—the most important place on earth.” We know that Jerusalem is a high point in the region. The temple was built on Mt. Moriah and would be visible to the people. I have not traveled myself to Israel, but I know that as of today the temple is not standing in all its glory as it once was. Are we to assume that this vision has already taken place?
Revelation 21 is thought to be the fulfillment of this prophecy. God brings forth a new Jerusalem “descending out of heaven from God. It shone with the glory of God and sparkled like a precious stone—like jasper as clear as crystal.” It will be a place of beauty and people from all over the world will go there to worship God. Our text today says people from many nations will come. This had to be strange for the people Isaiah was speaking to. Jerusalem was their city. Why would other nations come there?
I love the picture here of God giving the people what they asked for. They wanted to hear from God, but they didn’t want to hear his message directly again. It had really scared them in the wilderness. They thought they were going to die. Moses had become that spokesperson, but he wasn’t making the trek into the promised land with them. God would raise up another prophet or many others.
How would they know if it was a true prophet or just a false imposter? This is the answer. “If the prophet speaks in the Lord’s name but his prediction does not happen or come true, you will know that the Lord did not give that message.” Depending on the prophecy, it might take days, months, or years to know if a prophecy was from God. That could seem like a lifetime to be following the wrong message.
Jesus finished his instructions. Then what did he do? He went out, too. What a great teacher. Not only did he teach, but he also implemented. Talk about leading by example! It’s more than just using our words. It’s our actions, too. You’ve heard “actions speak louder than words,” right?
Beyond that, we can see Jesus as a great communicator. When John the Baptist’s followers asked him if he was the Messiah, Jesus could have just answered their question with a simple, “Yes.” But he gave them something to think about, to identify with, to remember happening. And then he tells them they’ll be blessed if they are not offended by him.
