Apparently Euodia and Syntyce were not getting along even though each of them was a loyal, hard-working church worker. Paul is asking the them to get along and for the church to help them.
Then he gives directions to that congregation that are helpful to us all these centuries later.
I'm used to making a to-do list. Paul is asking us to make a to-think list. Look at verse 8. Think about these things: whatever is honorable, just, pure, pleasing, commendable. Think about any excellence you witness, anything worthy of praise.
If our minds are full of such thoughts, how hard can the rest be? Couldn't a church that is thinking about the items on this list be able to keep of doing the things that we have learned to do, the things that we have seen in people like Paul?
Couldn't a church that is thinking about these things be able to rejoice in the Lord?
