Paul speaks of the money he is taking to Jerusalem as if it were a fruit that was collected for them. AT: "and have safely delivered this offering to them" (See: [[rc://en/ta/man/translate/figs-metaphor]])
This phrase means that Christ will bless Paul and the Roman believers. AT: "And I know that when I visit you, Christ will abundantly bless us" (See: [[rc://en/ta/man/translate/figs-explicit]])
