This passage was used by Jesus 1000 years after it was written to confound the wisdom of the religious teachers. In a sense, this was a fulfillment of its prophecy. But the truth of the passage speaks of a specific time as much as it speaks of an overall truth. Jesus is one of the Lord’s that it spoke of. God the Father is the other. Yet, the time when the two shall actively subdue the nations is still to come. And in another sense, when Jesus was incarnated, it already began. What one must truly take from this passage is not the time of events, but the nature of them. This passage reveals that God, at least, is a tandem being. He is both Lord and his own Lord. There are at least two aspects to his Lordness. These two interplay distinctly with each other and are outside of space and time. In fact, this is the specific part of the passage that Jesus chose to confound the teachers with. How can David call his descendant his Lord? We can look forward to a day when we can better understand this mystery. In the meantime, we can also know that God is, at least, two in one. We can know that there are two personalities who are in constant communication and submission, as we worship him.
