Verse by Verse Commentary

1. Verse 1 – Chapters 14 and 15 are a transition between the trumpet judgments and the last seven judgments (the bowl judgments). John is given a vision of the next step of God’s plan. Seven more judgments are going to be poured out upon the earth. These are described as the “last,” and “with them the wrath of God is finished.”

One of the main purposes of the tribulation is for God to pour out His righteous judgment upon a world that will be crazed with sin and rebellion. By this point, we have already seen fourteen judgments sent upon the earth. Now the end is nearing. After the final seven, that step of God’s plan will be finished and Jesus will then return.

2. The wrath of God – God is good and righteous, but He is not tolerant of sin. He is not apathetic or distant.

In the Chronicles of Narnia series, C.S. Lewis writes about Aslan (a lion representing Christ). He writes that Aslan is a good lion, but he is not a tame lion.

Our God is good, kind, loving, merciful, gracious, and patient. But that does not mean that He will not punish evildoers. Throughout the book of Revelation, we see that God’s mercy and justice are shown side by side. The very same plagues that are sent in judgment are also a manifestation of mercy. These supernatural signs are meant to wake up a world hardened by sin and turn them to repentance. However, they are not only manifestations of mercy. They are also clearly God’s wrath and judgment against sin.

The scope of these judgments should show us very clearly how much our Lord hates sin. Make no mistake. He is angry. Repeated and willful rebellion against His good commands is not met with silence. He offered the world a carrot many times. But if they won’t accept the carrot, then it is going to be the stick.

Romans 1:18 Bible verse

Salvation is available. Anyone who wants to escape that wrath can. Only one thing is necessary. Accept His Son.

John 3:36 – Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.

Application: Make sure that you are in right standing with God so that you will not have to face His wrath.

3. A sea of glass mingled with fire – John said that he saw what “appeared” to be a sea of glass mingled with fire. In Revelation 4:6 he describes it as “crystal.” He is unable to describe this amazing sight perfectly, because he had never seen anything like it on earth. And because he can’t describe it, he uses qualifiers like “appeared.” That was the best he could do with the limited language and experience available to someone from this world.

His very description seems to contradict itself. Glass is stationary, but a sea generally has waves and moves. And fire doesn’t mix well with water. Whatever John saw had qualities of each of these. Since John mentions it twice, this sea is prominent and has some deeply significant purpose. One day we will find out what that is.

1 Corinthians 13:12 – For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.

Now we see things dimly. We have just a glimpse of heaven and it is hard to understand. It is as though we are looking at a very poor mirror. One day we will see the Lord (and all of these other things) face to face and our comprehension will be far greater than it is now.

Application: Be diligent to study so that you can understand as much as you possibly can now about the Lord. Always pray and seek enlightenment from the Spirit in those difficult-to-understand areas.

4. Those who had conquered the beast – Martyred saints will be there next to the sea in heaven with the Lord. It is a great title which is given to them, “those who had conquered the beast.”

The beast gets his power from Satan himself. He and the false prophet will have very impressive supernatural powers. In addition to these powers, they will be backed up by the best technology and most powerful armies the world can provide.

And yet believers will be able to overcome these powers of evil. That victory will not be through force of arms. It will not be through subterfuge or sabotage.
