Westminster Larger Catechism

Repentance unto life is a saving grace,³²⁰ wrought in the heart of a sinner by the Spirit³²¹ and Word of God,³²² whereby, out of the sight and sense, not only of the danger,³²³ but also of the filthiness and odiousness of his sins,³²⁴ and upon the apprehension of God’s mercy in Christ to such as are penitent,³²⁵ he so grieves for³²⁶ and hates his sins,³²⁷ as that he turns from them all to God,³²⁸ purposing and endeavouring constantly to walk with him in all the ways of new obedience.³²⁹
