Romans 1:11-12

I long to see you so that I may impart to you some spiritual gift to make you strong— that is, that you and I may be mutually encouraged by each other's faith.

(v11-12, NIV)

Paul wants to see them and he wants to go to them. He wants them to know that he longs to see them. It's not as if he doesn't care for them. They may think so since he hasn't come to see them yet. Some may have circulated false claims that Paul didn't really care about them and if he did, he would've came to see them already. This is not true; he wanted to come to see them.

Why did he want to go to them? He wanted to impart some spiritual gift to them. He wanted to strengthen them through spiritual gifting. He wanted to help them and bless them through this. However, as he says that, he takes a step back to explain what he really means. He doesn't want to sound arrogant as if he's so big and powerful that they need him for this spiritual gifting. Rather, he desires for mutual encouragement. He wants them to be encouraged by him and he wants to be encouraged by them. This is a two-way relationship. The fact of the matter is, he needs them. The body of Christ is not made up of people like Paul simply giving and giving to others. Churches aren't made up of a number of leaders who only give to the rest of the church. There is a mutuality of encouragement going on between all members of the church. This is not a one-way thing, but there is mutuality.
