What does revelation of God's love mean?

Sadness is hallowed in one sense because of what it has produced, what it has worked out in the physical mind. But once its work is done, and it was only a test sent to prove whether you were strong enough to emerge from it into joy, once its work is done, you do not belong to it.

You belong to that perfect happiness, that perfect harmony, sadness and depression and loneliness are of the shadows only. 

Step forward into the light of understanding, into the revelation of the love of God. See to it then that you put on your strongest armour to fight the enemies that would approach. 

And if you call upon the Saviour, you will find that happiness, in its most beautiful form, contentment, will enter and remain a guest until it is turned into something stronger still.
