[I pray] that the sharing of your faith [with others, or possibly with Paul] will be effective when you fully realize all the good you can do for Christ.

'tis true he was formerly useless to you, but now he will be useful to us both:

But I was willing to do nothing without your consent, that your goodness would not be as of necessity, but of free will.

I, Paul, write this with my own hand: I will repay it (not to mention to you that you owe to me even your own self besides).

Having confidence in your obedience, I write to you, knowing that you will do even beyond what I say.

Also, prepare a guest room for me, for I hope that through your prayers I will be restored to you.
