=2.= The predominant attribute of justice, recognized as part of the Divine nature, forbids the thought that man should receive promises of reward for righteousness, and threats of punishment for evil deeds, if he possessed no power of independent action. It is no more a part of God's plan to compel men to work righteousness, than it is His purpose to permit evil powers to force His children into sin. In the days of Eden, the first man had placed before him commandment and law,[120] with an explanation of the penalty which would follow a violation of that law. No law could have been given him in righteousness had he not been free to act for himself. "Nevertheless thou mayest choose for thyself, for it is given unto thee, but remember that I forbid it,"[121] said the Lord God to Adam. Concerning His dealings with the first patriarch of the race, God has declared in this day, "Behold, I gave unto him that he should be an agent unto himself."[122] [120] Genesis ii, 17; Pearl of Great Price, Moses ii, 27-29; iii, 15-17. [121] Pearl of Great Price, Moses iii, 17. [122] Doctrine and Covenants, xxix, 35. =3.= When the brothers Cain and Abel brought their sacrifices before the Lord, the elder one became angry because his offering was rejected; then the Lord reasoned with Cain, and endeavored to teach him that he must expect results of his actions to follow in kind, good or evil, as he might elect:--"If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door."[123] [123] Genesis iv, 7. =4.= A knowledge of good and evil is essential to the advancement which God has made possible for His children to achieve; this knowledge can be best gained by actual experience, with the contrasts of good and its opposite before the eyes; therefore has man been placed upon the earth subject to the influence of good and wicked powers, with a knowledge of the conditions surrounding him, and the heaven-born right to choose for himself. The words of the prophet, Lehi, are particularly explicit: "Wherefore, the Lord God gave unto man that he should act for himself. Wherefore, man could not act for himself, save it should be that he was enticed by the one or the other.... Wherefore, men are free according to the flesh; and all things are given them which are expedient unto man. And they are free to choose liberty and eternal life, through the great mediation of all men, or to choose captivity and death, according to the captivity and power of the devil; for he seeketh that all men might be miserable like unto himself."[124] [124] II Nephi ii, 16 and 27; x, 23.
