“Where there is neither Greek nor Jew, circumcised nor uncircumcised, barbarian, Scythian, slave nor free, but Christ is all and in all.”
“but Christ is all and in all”
Christ takes down all walls that divide. There is no difference in wealth, condition, education, circumstance, or personality. All stand on the same level before God.
Jesus made this happen by his cross. All are equal at the foot of the cross. Whatever we are in other respects, Christ is all to us. God wants us to center around Christ, not our differences. As our new Head, He breaks down social barriers of pride, place, and circumstance. Race and culture evaporate in his presence. Union with Christ wipes out natural distinctions.
Regardless of religion, nationality, culture, or economic status, all Christians should live the transforming life of Christ.
It comes as a shock to religious people that all they need to be acceptable to God is the Lord Jesus Christ. There is no need for catechism, baptism, or joining a church. Christ is all we need for salvation.
Moreover, Christ is all we need for the Christian life. We do not get more of Him than we have. He is a person, and we do not receive a person on the installment plan (John 1:16). Since we received new life in Christ, we received Christ fully. All we need to do is learn to appropriate Him personally to our experience (2 Cor. 4:10; Phil. 1:20,21).
In our world of division, we need to remember that there are no distinctions in the body of Christ.
