Let them 'have the water of life'

Revelation 22:1-21
“Look, I am coming soon! Blessed is the one who keeps the words of the prophecy written in this scroll.”
Blessed are those who wash their robes, that they may have the right to the tree of life and may go through the gates into the city.
Jesus said "I am the Root and the Offspring of David, and the bright Morning Star".
This is all true, the angel says to John. 'He is coming soon. Make these things known.'
Then the vision of the angel fades - and it is Jesus himself who speaks.
The final statements are somewhat disjointed, but lack nothing in vigour. John affirms the truth of what he has written.
In the sternest terms of his Day, he warns against tampering with it.
His closing words are full of urgency.
The things he has described will happen soon. Christ's coming is imminent. The people's attitudes will be fixed. It will not be possible to change. In the end, those who are not saved will be lost; those who do not enter into eternal life and the presence of God will be shut out for ever.
So let all who are thirsty come. Let them 'have the water of life', for which there is no charge.
Why?
Blessed are those who keep the word of prophets.  Blessed are those who wash their robe. Wash through the blood of Jesus.
Jesus is coming soon! it is urgent thing to everyone in the world!
How?
I believed that all things John has written. Let us preach the word of God and keep obey His Words!
