Romans 15:27-29

It hath pleased them verily; and their debtors they are. For if the Gentiles have been made partakers of their spiritual things, their duty is also to minister unto them in carnal things. When therefore I have performed this, and have sealed to them this fruit, I will come by you into Spain. And I am sure that, when I come unto you, I shall come in the fulness of the blessing of the gospel of Christ.
