Romans 15:25-29

but now, I am going to Jerusalem serving the saints. For Macedonia and Achaia have been pleased to make a contribution for the poor among the saints in Jerusalem. Yes, they were pleased to do so, and they are indebted to them. For if the Gentiles have shared in their spiritual things, they are indebted to minister to them also in material things. Therefore, when I have finished this, and have put my seal on this fruit of theirs, I will go on by way of you to Spain. I know that when I come to you, I will come in the fullness of the blessing of Christ.
