What will happen when all things are subdued unto Christ?
When all things are subdued unto Christ, all principalities, powers, kingdoms, and even death come under His supreme rule. Then at a coming point in time, the Son Himself will be subject unto the One who put all things under Him, so that God may be all in all.
Les explains that this is mind-boggling because every word is the Word of God. He teaches that all principalities, powers, kingdoms, and even death will come under Christ's supreme rule after everything is subdued unto Him. Then, at a point in time—perhaps the onset of eternity—the Son will also be subject unto Him who put all things under Him, that God may be all in all. Les notes that after everything has been put under Christ's feet and God is all in all, a day is coming when even Christ will evidently give everything up to the Godhead. He says he must be careful and not compromise.
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.
