Here a temporary "house" or "tent" is a metaphor for a person's physical body and a permanent "building from God" is a metaphor for the new body that God will give believers after they die. (See: [[rc://en/ta/man/jit/figs-metaphor]])
This can be stated in active form. Alternate translation: "if people destroy our earthly house—the tent—we have" or "if people kill our bodies, we have" (See: [[rc://en/ta/man/jit/figs-activepassive]])
Here "house" means the same thing as "building from God." Here "hands" is a synecdoche that represents the human as a whole. This can be stated in active form. Alternate translation: "It is a house that humans did not make" (See: [[rc://en/ta/man/jit/figs-activepassive]] and [[rc://en/ta/man/jit/figs-synecdoche]])
