I must acknowledge the great evil that there is in sin, and in my sin; the malignity of its nature, and its mischievousness to me.
The sinfulness of sin.
O that sin may be shown to be sin to me, may be shown in its true colors; and that by the commandment I may see it to be utterly sinful, Romans 7:13(NASB) because it is lawlessness. 1 John 3:4(NASB)
By every willful sin I have in effect said, “I do not want this man to reign over me.” Luke 19:14(NASB) And, “Who is the LORD that I should obey His voice?” Exodus 5:2(NASB) And thus I have blasphemed the LORD, Numbers 15:30(NASB) and cast His laws behind my back. Nehemiah 9:26(NASB)
The foolishness of sin.
O God, You know my folly, and my wrongs are not hidden from You. Psalm 69:5(NASB) I was foolish in being disobedient, Titus 3:3(NASB) and my desires are foolish and harmful. 1 Timothy 6:9(NASB)
Foolishness was bound up in my heart when I was a child; Proverbs 22:15(NASB) for though vain man would be wise, he is born like the foal of a wild donkey. Job 11:12(KJV)
My way has been foolish, Psalm 49:13(NASB) and in many instances I have acted very foolishly. 2 Samuel 24:10(NASB)
I have been senseless and ignorant, even like a beast before God. Psalm 73:22(NASB)
