Paul writes encouragement and admonition to the church in Corinth.
Factions were common in Judaism. Paul encouraging all of them to focus on Jesus, their foundation, would have been a refreshing change from the more common partisan bickering.
God values unity.
People tend to be clannish, wanting to stick closest with those who are just like them- right.
Be a unifier, not a divider. And be sure that the common ground is Christ.
Divide and conquer is a popular political tactic, but it can seep its way into the church. Resist this. Unify around Christ.
Father, help my heart love unity as you do.
