Romans 15:19-21

with the power of signs and wonders, [and all of it] in the power of the Spirit. So [starting] from Jerusalem and as far away as Illyricum, I have fully preached the gospel [faithfully preaching the good news] of Christ [where it had not before been preached]. Accordingly I set a goal to preach the gospel, not where Christ’s name was already known, so that I would not build on another man’s foundation; but [instead I would act on this goal] as it is written [in Scripture], “THEY WHO HAD NO NEWS OF HIM SHALL SEE, AND THEY WHO HAVE NOT HEARD [of Him] SHALL UNDERSTAND.” [Is 52:15]
