Commentary of Charles Spurgeon, Adam Clarke & Matthew Henry
First,
I thank my God through Jesus Christ for you all, 
that your faith is spoken of throughout the whole world.
For God is my witness, whom I serve with my spirit in the gospel of His
Son,
that without ceasing I make mention of you always in my prayers;
Making request, if by any means now at length I might have a prosperous journey by the will of God to come unto you.
For I long to see you, that I may impart unto you some spiritual gift, to the end ye may be established; That is, that I may be comforted together with you by the mutual faith both of you and me.
Vs.8-12

he prayed for them; not only for all saints in general, but he made express
mention of them. It is not unfit sometimes to be express in our prayers for
particular churches and places; not to inform God, but to affect ourselves.
That I may impart unto
you. - He received, that he might communicate.
Paul prayed about that matter, and we may pray about our journeys.
