Many promises and prophecies fill the Bible, and the Lord has done everything He promised and prophesied, and for those things that remain, John wrote,
“Then he said to me, ‘These words are faithful and true.’ And the Lord God of the holy prophets sent His angel to show His servants the things which must shortly take place” (Revelation 22:6).
We can know that the words of the Book of Revelation, and the rest of the Bible, are faithful and true words, because the same God who spoke through His holy prophets and always remained true to His words back then, sent His angel to show John and all God’s servants the things in the Book of Revelation.
Therefore, the Book of Revelation speaks the truth. Let us comply ourselves with everything that He tells us to do in it.
