Revelation 3:5: Happy for ever happy

Happy for ever happy I,
If suffer'd with my Lord to die!
O might I gain the victor's right,
The robe of pure unspotted white,
And wear the saints' celestial dress,
The Lord my glorious righteousness.

Soon as I win the vast reward,
The joy for conquerors prepared,
Wrote in the volume of the Lamb
Thou never wilt blot out my name,
But me before Thy Father own,
And rank with angels round Thy throne.
