The Power by Which to Become a Son of God--Oath and Covenant Explained

5  And they deny the power of God, the Holy One of Israel; and they say unto the people: Hearken unto us, and hear ye our precept; for behold there is no God today, for the Lord and the Redeemer hath done his work, and he hath given his power unto men; 6  Behold, hearken ye unto my precept; if they shall say there is a miracle wrought by the hand of the Lord, believe it not; for this day he is not a God of miracles; he hath done his work. 7  Yea, and there shall be many which shall say: Eat, drink, and be merry, for tomorrow we die; and it shall be well with us. 8  And there shall also be many which shall say: Eat, drink, and be merry; nevertheless, fear God—he will justify in committing a little sin; yea, lie a little, take the advantage of one because of his words, dig a pit for thy neighbor; there is no harm in this; and do all these things, for tomorrow we die; and if it so be that we are guilty, God will beat us with a few stripes, and at last we shall be saved in the kingdom of God. 9  Yea, and there shall be many which shall teach after this manner, false and vain and foolish doctrines, and shall be puffed up in their hearts, and shall seek deep to hide their counsels from the Lord; and their works shall be in the dark. (Book of Mormon | 2 Nephi 28:5 - 9) 21  (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:) (New Testament | Hebrews 7:21) 4 The Lord hath sworn (oath), and will not repent, Thou art a priest for ever after the order of Melchizedek. Psalms 110:4–5 And no man taketh this honour unto himself, but he that is called of God, as was Aaron. Hebrews 5:4
