1 Samuel 10
O keep me while I tarry on this earth, in daily serious breathings after you, and in a believing, affectionate walking with you: and when you come, O let me be found so doing, not hiding my talent, nor serving my flesh, nor yet asleep with my lamp unfurnished, but waiting and longing for my Lord’s return.
When you come to die it will be a sore matter of regret to you that you did not serve your Master more. I never heard of a Christian who died lamenting he had done too much for Christ, been too earnest, too indefatigable, and so had shortened his life. There have been men who have shortened their lives for Christ, but even when chidden by their friends they have only gone on working still, and have rejoiced to die for his dear sake.
