“My sin is ever before me” (Psalm 51.3). A humble soul sees that he can stay no more from sin, than the heart can from panting, and the pulse from beating. He sees his heart and life to be fuller of sin, than the firmament is of stars; and this keeps him low. He sees that sin is so bred in the bone, that till his bones, as Joseph’s, be carried out of the Egypt of this world, it will not out. Though sin and grace were never born together, and though they shall not die together, yet while the believer lives, these two must live together; and this keeps him humble.
