Charles Ellicott Commentary 1 Corinthians 15:28

"And when all things have been subjected unto him, then shall the Son also himself be subjected to him that did subject all things unto him, that God may be all in all." — 1 Corinthians 15:28 (ASV)

That God may be all in all.—In these words is expressed the complete redemption both of the race and of the individual. It is the great and sublime conclusion to which the moral enthusiasm and the earnest logic of the previous argument have necessarily brought us.
