Here "kingdom of God" refers to God's rule as king. This can be stated in active form. Alternate translation: "God will take his kingdom away from you and will give it to a nation that produces the kingdom's fruits" or "God will reject you, and he will be king over people from other nations that produce the kingdom's fruits" (See: [[rc://en/ta/man/jit/figs-metonymy]] and [[rc://en/ta/man/jit/figs-activepassive]])
