Paul reminded the Ephesian elders of his ministry among them when he taught publicly and from house-to-house,
“testifying to Jews, and also to Greeks, repentance toward God and faith toward our Lord Jesus Christ” (Acts 20:21).
He spoke to anyone, whether Jew or Greek, of their need to repent toward God and of their need to have faith toward our Lord Jesus Christ.
That is the message of the Bible, and especially of the New Testament. Have you heard that message? Have you obeyed it?
