Will Christ eventually hand everything back over to the Godhead?

Les teaches that this passage is mind-boggling and every word is the Word of God, so it cannot be sloughed off. He reads that when all things shall be subdued unto Him—all principalities, powers, kingdoms, and even death come under His supreme rule—then there is another time word. There is coming a point in time, which he thinks is the onset of eternity, when the Son also Himself shall be subject unto Him who put all things under Him, that God may be all in all. Les says you can wake up in the middle of the night and consider that verse. After everything has been put under Christ's feet and He has become all in all, there is still coming a day when even Christ will evidently give everything up to the Godhead. Les notes he must be careful because highly educated theologians are listening, and he does not want to get into hot water unnecessarily, but he will not compromise.
