1Corinthians 9:24

Do you not know that the runners in a stadium all race, but only one receives the prize?  Run in such a way that you may win.

11 Corinthians 1:8-10

He will also confirm you to the end blameless in the the day of our Lord Jesus Christ.  God is faithful; by Him you were called into fellowship with His Son, Jesus Christ our Lord.  Now I urge you brothers (sisters), in the name of our Lord Jesus Christ, that you say the same thing, that there be no divisions among you, and that you be united with the same understanding and the same conviction.
