With us there is no gray fearing, 
With us no aching for lack! 
For the morn it is always nearing, 
And the night is at our back. 
At times a song will fall dumb, 
A thought-bell burst in a sigh, 
But no one says, 'He will not come!' 
She says, 'He is almost nigh!' 
 
The thing you call a sorrow 
Is our delight on its way: 
We know that the coming morrow 
Comes on the wheels of to-day! 
Our Past is a child asleep; 
Delay is ripening the kiss; 
The rising tear we will not weep 
Until it flow for bliss.
George MacDonald
