Summary: Most of the people who knew Jesus personally are now dead, and a second generation of Christians has grown up. The gospel claims that Jesus is King of the world and is coming back soon to claim His domain. But the years pass, and still He does not come.
Purpose: To lift up the glory of Christ’s forgiveness.
Aim: I want the listener to praise God for the privileges of salvation.
INTRODUCTION: When John wrote the book of Revelation Jesus’ resurrection had happened about sixty-five years earlier. Most of the people who knew Jesus personally are now dead, and a second generation of Christians has grown up. The gospel claims that Jesus is King of the world and is coming back soon to claim His domain. But the years pass, and still He does not come.
Now a madman has become emperor of Rome who actually believes the poets’ praises that he is a god incarnate. He likes to be addressed as "Our Lord and God." He has decreed that anyone who holds public office, anyone who testifies in court--which means practically everyone--must offer a pinch of incense to the emperor’s guardian spirit and declare "Caesar is Lord." If a person refuses to worship the emperor, he may lose his job, his home, or even his life.
This is not the only threat to Christians in 95 AD. Within the churches are some members who want to take control and twist the gospel to suit them. Danger without and danger within--is God really in control? In part to answer this question for the embattled Christians in the first century and every century since, God gave a series of visions to the last living Apostle named John. It is called "The Revelation of Jesus Christ, which God gave Him to show to His bond-servants, the things which must soon take place..." (Revelation 1:1).
The promised coming of Christ gives us confidence that God IS in control, and it also gives us the motivation to get busy serving this wonderful Lord.
So far we have seen four of the nine responsibilities that Christians have in light of His soon return. Today we will look at two more.
1:1-20 I. John’s Vision of the Past "the things which you have seen"
2:1-5:14 II. Christ’s Vision of the Present "the things which are"
Ch.6-22 III. John’s Vision of the Future "things which will take places"
6-7; 12-14 A. Satan’s war against God’s creation- the first six seals
8-11; 13:11-18; 15-18 B. Savior’s war against Satan: The wrath of God- the seventh seal
Ch.19-20 C. The worship of God
Ch.21-22:5 D. The wonder of eternal bliss
22:6-21 E. The responsibilities of those going to heaven
Vs.6-7 1. Be alert "I am coming quickly"
Vs.8-9 2. Worship God alone "Worship God."
Vs.10-11 3. Spread God’s message "Do not seal...the prophecy"
Vs.12-13 4. Live in light of God’s presence "I am the Alpha and the Omega"
Vs.14-15 5. Rejoice in the blessings of salvation "those who wash their robes"
This verse points back to chapter 7 verse 14: "These are the ones who come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb" (Revelation 7:14).
The word ROBES refers to long stately robes. 
Christians are pure and clean because they have been immersed in the blood of Christ: "how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?" (Hebrews 9:14).
