7. What does it mean to “observe the oneness of the spirit”?

⁷ Although Jehovah has declared his anointed ones righteous as sons and the other sheep righteous as friends on the basis of Christ’s ransom sacrifice, personal differences will arise as long as any of us are alive on earth in this system of things. (Rom. 5:9; Jas. 2:23) Otherwise there would have been no need for the inspired advice for us to continue “putting up with one another.” How is unity with fellow believers achieved? We need to develop “complete lowliness of mind and mildness.”
