29 Nov 1 Corinthians 1:10

10 Now I exhort you, brethren, by the name of our Lord Jesus Christ, that you all agree and that there be no divisions among you, but that you be made complete in the same mind and in the same judgment. 

Corinth was an interesting city. It was full of false gods and idols as well as temples and shrines. Corinth was a very diverse city with people of different backgrounds, much like our schools and workplaces are today. Because there were so many differences, the Corinthian Christians were arguing all the time! Paul had to teach them to be of one mind in Christ. How can you help with unity and be of one mind with others?
