I Corinthians 15:27-28

²⁷For He has put all things in subjection under His feet. But when He says, “All things are put in subjection,” it is evident that He is excepted who put all things in subjection to Him. ²⁸When all things are subjected to Him, then the Son Himself also will be subjected to the One who subjected all things to Him, so that God may be all in all.
