Numbers 16:41

The man that hath not studied human nature very closely, and yet more especially hath not been taught by the HOLY GHOST the great evil of sin, and the plague of his own heart, will be astonished that a mutiny after such a tremendous judgment as had but just taken place, should, again break out. The earth was scarce closed. The fire of GOD was still, as it were, burning before them. The shrieks of the people buried alive were still sounding in their ears. Reader, I pray GOD that such a view of human nature, and the hardness and obduracy of the heart, may in the hand of the LORD teach us, that nothing short of GOD'S HOLY SPIRIT can soften and conquer the soul. Oh LORD! write upon my mind and enforce its observance, that precept of the apostles: Hebrews 3:12.
