When the apostles came together, after the Lord’s ascension, they came together with one mind in prayer. When Paul exhorted the Corinthians to be of the same mind and judgment there was a special reason for such. Our varied ideologies, our multitude of “baggage” brings those in Christ together as one. This forming, this forging, reforms in us a new way of thinking – a thinking that corresponds to Galatians 2:20. I have been crucified with Christ and it is no longer I who live, but Christ lives in me; and the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.
This is the Lord’s unity. Lay down all opinions, never bring them up or in where they might divide. Hold on to the Lord for He is the only Lord and we are not (Luke 6:46; John 8:43).
