2 Nephi 4:(4) 26-29

4. For the Lord God hath said: Inasmuch as ye shall keep my commandments, ye shall prosper in the land; and inasmuch as ye will not keep my commandments ye shall be cut off from my presence.

26. O then, if I have seen so great things, if the Lord in his condescension unto the children of men hath visited men in so much mercy, why should my heart weep and my soul linger in the valley of sorrow, and my flesh waste away, and my strength slacken, because of mine afflictions?
27. And why should I yield to sin, because of my flesh? Yea, why should I give way to temptations, that the evil one have place in my heart to destroy my peace and afflict my soul? Why am I angry because of mine enemy?
28. Awake, my soul! No longer droop in sin. Rejoice, O my heart, and give place no more for the enemy of my soul.
29. Do not anger again because of mine enemies. Do not slacken my strength because of mine afflictions.

Matthew 23:23-24

23. Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
24. Ye blind guides, which strain at a gnat, and swallow a camel.

Alma 42:15

15. And now, the plan of mercy could not be brought about except an atonement should be made; therefore, God himself atoneth for the sins of the world, to bring about the plan of mercy, to appease the demands of justice; that God might be a perfect, just God, and a merciful God also.
