The kine unguided went 
By the directest road; 
When the Philistines homeward sent 
The ark of Israel's God.  
 
Lowing they passed along, 
And left their calves shut up; 
They felt an instinct for their young, 
But would not turn or stop.  
 
Shall brutes, devoid of thought, 
Their Maker's will obey; 
And we, who by his grace are taught, 
More stubborn prove than they?  
 
He shed his precious blood 
To make us his alone; 
If washed in that atoning flood 
We are no more our own.  
 
If he his will reveal, 
Let us obey his call; 
And think whate'er the flesh may feel, 
His love deserves our all.  
 
We should maintain in view 
His glory, as our end; 
Too much we cannot bear, or do, 
For such a matchless friend.  
 
His saints should stand prepared 
In duty's path to run; 
Nor count their greatest trials hard, 
So that his will be done.  
 
With Jesus for our guide, 
The path is safe though rough 
The promise says, I will provide, 
And faith replies, Enough!
John Newton
