The more godly a man is the more doth he feel the battle between the flesh and the spirit. Hereof cometh those lamentable complaints in the Psalms and other Scriptures. It profiteth us very much to sometimes feel the wickedness of our nature, and corruption of the flesh, that we may be wakened and stirred up to call upon Christ. So a Christian is made to see Jesus a wonderful Creator, who out of the heaviness can make joy; of terror, comfort; of sin, righteousness; and of death, life. This is our Ground and Anchor-hold, that Christ is our only and perfect Righteousness.
