Mt 9:4 And Jesus knowing their thoughts said, Wherefore think ye evil in your hearts? 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, Heb 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. Mt 12:35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. Mt 7:11 If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him? Mr 7:23 All these evil things come from within, and defile the man. 1Co 13:5 Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; 1Ti 6:4 He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings, 1Ti 6:10 For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows. Heb 3:12 Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God. Jas 4:16 But now ye rejoice in your boastings: all such rejoicing is evil. Ps 44:21 Shall not God search this out? for he knoweth the secrets of the heart. Eze 38:10 Thus saith the Lord GOD; It shall also come to pass, that at the same time shall things come into thy mind, and thou shalt think an evil thought: 2Co 10:5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ; Sin cannot be restricted only to thoughts where the will is engaged to carry out those thoughts. It is sin when we do not resist evil thoughts but instead choose simply to contemplate upon them regardless if we determine to put them into external acts or not. We are commanded to bring every thought into obedience to Christ and when we fail to do that we sin. The thought world can be an absolute den of iniquity never volitionally carried out into actions but volitionally permitted to be contemplated as day dreams. Hence, sin occurs when we fail to resist sinful thoughts but choose to merely speculate and surmise over them. A Poor man may permit his thought life to dream of riches and imagine all kinds of sinful thoughts and yet never be provided any providential circumstance to put his dreams into actions or choose to actually commit such thoughts to actions. The heart of man is evil and therefore Jesus describes man as "being evil" and talks about the "evil treasure" or his heart from which "evil" things are derived in his thought life. Romans 8:7 literally speaks of the "MINDSET" which is at war against God and is not subject to the law of God and NEITHER INDEED CAN BE" as the STATE of the lost man by nature. Love "thinketh no evil" or else it ceases to be love and therefore to think evil is something that a person dominated by love CANNOT DO! Hence, God has a righteous heart which is incapable of thinking evil. Therefore, to be able to think evil proves man has a sinful heart and thus "being evil."
