"I, John, am the one who heard and saw these things. And when I had heard and seen them, I fell down to worship at the feet of the angel who had been showing them to me. But he said to me, 'Do not do it! I am a fellow servant with you and with your brothers the prophets and of all who keep the words of this book. Worship God!'" NIV translation
John gives us a look at his human side as he falls down to worship the angel who had been giving him the tour. He was immediately corrected and reminded that we are only to worship God. It is comforting to know that the people that God used were, for the most part, common folks just like you and me. They made mistakes just as we do but God's grace is great enough for all of our sins!
"Then he told me, 'Do not seal up the words of the prophecy of this book, because the time is near. Let him who does wrong continue to do wrong; let him who is vile continue to be vile; let him who does right continue to do right; and let him who is holy continue to be holy.'" NIV translation
John could have kept all of the things that he had been shown to himself but the angel told him not to. He shared it with the church but, today, it seems that most church leaders will not teach it to their congregations.
Many, in fact, "seal up" the words instead of showing people the hope that is contained in the Book of Revelation.
"'Behold, I am coming soon! My reward is with me, and I will give to everyone according to what he has done.'" NIV translation
Here, we see a promise from Jesus and that promise is that He will reward His people for what they have done. In Luke 10:7, Jesus told the seventy-two that a "worker deserves his wages" and that is the promise that we see fulfilled in this verse. This is often referred to as "the second judgment" or the "judgment of rewards". Although Jesus does not tell us what those rewards are, we can be sure that they are awesome!
"'I am the Alpha and the Omega, the First and the Last, the Beginning and the End.'" NIV translation
From the first revelation in Genesis to the final chapter here, Jesus has always been there and in control. Even through the darkest times that John has told us about, He is still God and He is in control.
