We are told in 2 Timothy 3 verses 16 that "all Scripture has been breathed out by God". This includes the book of Revelation which is known in the Greek as 'the Apocalypse'. It was as its first verse tells us given to the Lord Jesus Christ by his Father who showed our Lord the matters "revealed" in that book. But having received those wonderful matters Jesus 'reveals' those matters via his angel through John the Apostle to all believers. In Revelation we have the only book in the Bible directly given to believers by the Lord Jesus Christ (1 verse 1) and encompassing blessings on the diligent readers (v3). It contains letters of advice in chapters 2-3 from the Lord which are portrayed in the opening vision of 1verses 9-20,. Each of the seven ecclesias in Turkey are told what's wrong with their attitude, and also they receive commendation for their successes. The 7 letters all emphasise faithful works that are necessary to please our Father and His Son. These works are seen in the faithful lives of His children as they strive to walk to the Father's kingdom guided daily by the energy drawn from the love of the Father and His Son and given to us through the Word of the Almighty. From this amalgam of instructions we are to be both warned and encouraged; in order for us to, like our Lord 'overcome' the world (2 verses 26-27) and so be blessed to inherit the Kingdom.
