I think my soul never was in ...

I think my soul never was in such an agony before. I felt no restraint, for the treasures of divine grace were opened to me. I wrestled for absent friends, for the ingathering of souls, for multitudes of poor souls, and for many that I thought were the children of God, in many distant places. I was in such an agony, for half an hour before sunset, till near dark, that I was all over wet with sweat: but yet is seemed to me that I had wasted away the day, and had done nothing. Oh!, my dear Savior did sweat blood for poor souls!

Saw so much of the wickedness of my heart that I longed to get away from myself...I felt almost pressed to death with my own vileness. Oh what a body of death is there in me...Oh the closest walk with God is the sweetest heaven that can be enjoyed on earth!

God designs that those whom He sanctifies...shall tarry awhile in this present evil world, that their own experience of temptations may teach them how great the deliverance is, which God has wrought for them.
