What does Revelation 21:26 mean?

According to this verse, the kings of the earth will bring the glory and the honor of the nations into New Jerusalem. Isaiah 60:11 predicts: "Your gates shall be open continually; day and night they shall not be shut, that people may bring to you the wealth of the nations, with their kings led in procession."

We cannot be explicitly sure what the term "glory and honor of the nations" represents. Perhaps the regenerate kings will present the best works of the millennial kingdom to be exhibited in New Jerusalem. Perhaps they will be paying homage to God. Of course, all that is accomplished as worth presenting to God is achieved only by God's grace and Christ's strength. Jesus said, "Apart from me you can do nothing" (John 15:5). What the kings bring to New Jerusalem, they had first received from our heavenly Father. James wrote, "Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shadow due to change" (James 1:17).
