Labour to know God

"Labour to know God, and to be affected with his attributes, and always to live as in his sight.—No man can know sin perfectly, because no man can know God perfectly. You can no further know what sin is than you know what God is, whom you sin against; for the formal malignity of sin is relative, as it is against the will and attributes of God. The godly have some knowledge of the malignity of sin, because they have some knowledge of God that is wronged by it. The wicked have no practical, prevalent knowledge of the malignity of sin, because they have no such knowledge of God. They that fear God will fear sinning; they that in their hearts are bold irreverently with God, will, in heart and life, be bold with sin: the atheist, who thinks there is no God thinks there is no sin against him. Nothing in world will tell us so plainly and powerfully of the evil of sin, as the knowledge of the greatness, wisdom goodness, holiness, authority, justice, truth, &c. of God. The sense of his presence, therefore, will revive our sense of sin’s malignity."
