'Message' in the Bible

but at the proper time has disclosed his message in the proclamation [with] which I was entrusted according to the command of God our Savior,

holding fast to the faithful message according to the teaching, in order that he may be able both to exhort with sound instruction and to reprove those who speak against [it].

sound message beyond reproach, in order that {an opponent} may be put to shame, [because he] has nothing bad to say concerning us.
