As it is written, Jacob have I loved, but Esau have I hated.
To sin because mercy abounds is the devil's logic. He that sins because of mercy is like one that wounds his head because he hath a plaster, he that sins because of God's mercy shall have judgment without mercy. Mercy abused turns to fury. Nothing sweeter than mercy when it is improved, nothing fiercer when it is abused; nothing colder than lead when it is taken out of the mine, nothing more scalding than lead when it is heated; nothing blunter than iron, nothing sharper when it is whetted. "The mercy of the Lord is upon them that fear Him." Mercy is not for them that sin, and fear not; but for them that fear, and sin not.
