'Preaching the Gospel' in the Bible

But Paul was not at all in favor of taking someone who had left them and refused to continue on in the work [of preaching the Gospel] when they were in Pamphylia. [See 13:13].

And we have sent [i.e., are sending] with him the brother who is praised throughout all the churches for [his work in] preaching the Gospel [Note: This "brother" cannot be identified with any certainty].

But you are aware [I am sure] that when I first came preaching the Gospel [message] to you, I had a physical handicap.

As you Philippians also know, during the early days of [my] preaching the Gospel [in those regions], when I left Macedonia [Note: This was the northernmost province of Greece], no church shared with me in the matter of giving and receiving [i.e., financial help], except you only.
