I Corinthians 1:8-10

who will also confirm you to the end, that you may be blameless in the day of our Lord Jesus Christ. God is faithful, by whom you were called into the fellowship of His Son, Jesus Christ our Lord. Now I plead with you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and that there be no divisions among you, but that you be perfectly joined together in the same mind and in the same judgment.
