God's love and care for his people never fails.

Revelation 6:7-16
Fourth seal opened: Voice of the 4 living creature say, "Come!" Pale horse! Its rider was named Death and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague, and by the wild beasts of the earth.
Open the 5th seal, under the altar the souls of those who had been slain because of the word of God and the testimony they had maintained. Each of them was given a white robe, and they were told to wait a little longer, until the number of their fellow servants and brothers who were to be killed as they had been was completed.
Sixth seal: Great earth quake, the sun turned black like sackcloth made of goat hair, the whole moon turned blood read, and the stars in the sky fell to earth. The sky receded like a scroll, rolling up.
All the free men hid in caves and among the rocks of the mountains. The great day of their wrath has come, and who can stand?
On the heels of conquest come slaughter, famine and disease - the classic judgments of God so often predicted by the prophets.
But no matter what the disaster, God is in control. His love and care for his people never fails.
In apocalyptic language John depict the disintegration of the fixed and stable world we know.
Why?
The end of world will come when the servants and brothers who were to be killed as they had been was completed, so there will be many Christians be persecuted before Jesus comes again.
How?
Be faithful to the Lord, for his love endure forever and his care for his people never fails.
