Gen. 6:5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. Ge 8:21 And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man’s sake; for the imagination of man’s heart is evil from his youth; neither will I again smite any more every thing living, as I have done. Jer 17:9 The heart is deceitful above all things, and desperately wicked: who can know it? Mt 15:19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies: Mr 7:21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, Mr 7:23 All these evil things come from within, and defile the man. Mt. 5:21 ¶ Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment: 22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: Mt. 5:28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. In light of these scriptures is it possible to sin only IN THE HEART without EXTERNALLY committing murder and adultery? Is there any heart that does not "come short" of the glory of God? Remember, to come short is to fail to measure up to God's own personal righteousness, which is his HOLINESS or the "glory of God."
