Paul tried to relate the Gospel without being offensive in Athens, by quoting Greek poets and bringing a message about their unknown god, yet few believed. Later we see Paul preaching the Gospel more simply and letting God convict the hearer. Paul went to Jerusalem even though he would no doubt be in danger and suffer. Truly, Paul did all things for the sake of the Gospel, and, like Jesus, made loving the lost his primary priority.
