Obviously we are supposed to be preaching the gospel (cf. Mark) and making disciples (cf. Matthew) but what else does that mean?
repentance and forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem.
Luke 24
It means preaching repentance and forgiveness. That’s the gospel, you (whoever you are) may have 100% forgiveness if you will simply turn to Jesus.
Will you?
