Firstly, we are commanded to “accept one another.” What does this mean, and what does it not mean? To gain some insight, consider the two preceding verses (5-6). “May the God who gives endurance and encouragement give you the same attitude of mind toward each other that Christ Jesus had, so that with one mind and one voice you may glorify the God and Father of our Lord Jesus Christ.”

I believe that what Paul is saying here is that accepting one another produces a spirit of unity in the body of Christ
