“For ‘He has put all things under His feet.’ But when He says ‘all things are put under Him,’ it is evident that He who put all things under Him is excepted. Now when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.”
For “He has put all things under His feet.”
This phrase is a quotation from Psalm 8:6. Jesus will reign until He puts all enemies under His feet.
But when He says “all things are put under Him,” it is evident that He who put all things under Him is excepted.
The person who subdues in Psalm 8 is man, but a special “Man” in particular – the man Christ Jesus.
Now when all things are made subject to Him,
There will come a time when all creation is subject to Jesus. He will finish His work of subduing lost creation. He will put all creation under His rule; He will be King Jesus, King of the Universe.
then the Son Himself will also be subject to Him who put all things under Him,
The Son will subject Himself to the Father forever. This is a working subordination of the Son to the Father, not a subordination in His essential character and being, for He is co-equal with the Father in His essence.
that God may be all in all.
Deliverance of the Kingdom to the Father at the end of time will complete the purpose of creation – that God may be all in all. “All in all” means that all things depend on God. The purpose of creation is God-centeredness, not man-centeredness. God is everything to everyone.
The purpose of time and eternity is God-centeredness.
God’s purpose for creation is His own glory. There will come a day when all creation, all people, all situations will depend on God. He will be everything to everyone. Heaven will center in God for all eternity. God is the source, the means, and the purpose of creation.
Ro 11:36, “For of Him and through Him and to Him are all things, to whom be glory forever. Amen.”
