Sabbath a' Brakel: On Sin

There is no sin from which a regenerated person is safeguarded in an absolute sense. Nobody can say: "I shall never fall into that sin." A person will never be delivered from the indwelling corruption of his nature. It will always prevent and defile that which is good, always stir up lusts, and daily cause a man to offend in many things, doing so either out of carelessness, or due to the sudden occurrence of an event (IV: 255).
