Romans 15:22

And I want you to be aware, brothers, of how frequently I [had] planned to visit you (but was prevented from doing so until now). I wanted to come in order to bear some fruit [i.e., make additional converts] among you, just as I have done among the other Gentiles [i.e., unconverted people].

But brothers, after we were separated from you for a short time --- in person but not in spirit --- we became all the more eager [to come to you] and strongly desired to see you in person. [Note: The word "separated" here denotes the traumatic experience of a child being forcibly removed from its parents. It had been about six months since Paul left Thessalonica under adverse circumstances].
