The different success of the gospel. 
 
1 Cor. 1:23,24; 3:6,7; 2 Cor. 2:16.  
 
Christ and his cross is all our theme; 
The myst'ries that we speak 
Are scandal in the Jew's esteem, 
And folly to the Greek. 
 
But souls enlightened from above 
With joy receive the word; 
They see what wisdom, power, and love 
Shine in their dying Lord. 
 
The vital savor of his name 
Restores their fainting breath; 
But unbelief perverts the same 
To guilt, despair, and death. 
 
Till God diffuse his graces down, 
Like showers of heav'nly rain, 
In vain Apollos sows the ground, 
And Paul may plant in vain.
Isaac Watts
