What things come under Christ's supreme rule?
All principalities, powers, and kingdoms, and even death itself, come under Christ's supreme rule. This occurs after everything has been subdued unto Him. Scripture presents this subjection as a future point in time, leading to the Son also being subject to the One who put all things under Him, so that God may be all in all.
Les explains that this is mind-boggling: all principalities, powers, kingdoms, and even death are going to come under Christ's supreme rule. This happens after everything has been subdued unto Him. Then there is another time word, showing a coming point in time—whether at the onset of eternity, as Les thinks, or whenever—when the Son also Himself will be subject unto Him who put all things under Him, that God may be all in all. Les says that after Christ has put everything under His feet and become all in all, there is still coming a day when even Christ is evidently going to give everything up to the Godhead.
And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
