30:24 Amidst the constant storm of opposition, the clamor of enemies, and the desertion of friends the intrepid apostle almost lost heart. But he looked back to Calvary and with new ardor pressed on to spread the knowledge of the Crucified. He was but treading the blood-stained path that Christ had trodden before him. He sought no discharge from the warfare till he should lay off his armor at the feet of his Redeemer.
