'Tis seen its loved support to clasp 



With such tenacity of grasp, 



We M-onder that such strength should dwell 



In such a small and simple shell. 



And is not this a lesson -worth 



The study of the sons of earth ? 



Who need a Rock so much as we ? 



Ah ! who to such a Rock can flee ? 



A Rock to strengthen, comfort, aid, 



To guard, to shelter, and to shade ; 



A Rock, whence fruits celestial grow, 



And whence refreshing waters flow. 



No rock is like this Rock of ours : 



Oh ! then, if you have learned your powers 



By a just rule of estimate ; 



If justly you can calculate, 



How great your need, your strength how frail, 



How prone your best resolves to fail. 



When humble caution bids you fear 



A moment of temptation near. 



Let wakeful memory recur 



To this your simple monitor, 



And wisely shun the trial's shock 



By clinging closely to your Rock. 



Need it be told who that Rock is ? It is the only 

 Mediator between God and man. Cleaving to him 

 with " full purpose of heart," we are safe for time and 

 eternity. For " who," says the apostle, " shall sepa- 

 rate us from the love of Christ? shall tribulation, or 

 distress, or persecution, or famine, or nakedness, or 

 peril, or sword? As it is written. For thy sake we 

 are killed all the day long ; we are accounted as sheep
