Hallucinative Perceptions

I saw the lord and he is high and lifted up
I saw the lord and his glory fills my life
To God be the glory - for the things he has done
With his blood he saved me - with his power he raised me
I saw a new heaven - I saw a new earth
I saw the holy city and aren't a hallucinative perceptions
I hear a great voice: The death shall be no more
The first things are passed away
And aren't a hallucinative perceptions
Help me to mortify my flesh
