who are these??

Who are these which are arrayed in white robes?
Who are these, and from where do They come?

These are these who came out (x2)
These are they who came out from of a great tribulation, and
They have washed their robes, and made them white (x3)
In the blood of the lamb

-Song by Dan Ricciardelli

Through all the trials and tribulation in life, let our hearts be stayed focus on you. Always
let us have clean hands and pure hearts, and with what we wear washed and made white

And the only way to do that is through the blood of the Lamb, and living in the life of the lamb
In the tribulation, keep staying in the life of the lamb. Tats the only way to pull through the great tribulation
