Why are things so hard for us in this life?  Could it be so we understand the price paid for us?
 The angels look at the mystery of salvation in wonder and want to understand, but can't.

There is singing up in Heaven such as we have never known,
Where the angels sing the praises of the Lamb upon the throne,
Their sweet harps are ever tuneful, and their voices always clear,
O that we might be more like them while we serve the Master here!

But I hear another anthem, blending voices clear and strong,
"Unto Him Who hath redeemed us and hath bought us," is the song;
We have come through tribulation to this land so fair and bright,
In the fountain freely flowing He hath made our garments white.

Holy, holy, is what the angels sing,
And I expect to help them make the courts of heaven ring;
But when I sing redemption's story, they will fold their wings,
For angels never felt the joys that our salvation brings.
