Moroni 7: 21,22,25,27,29,30,36,37
21 And now I come to that faith, of which I said I would speak; and I will tell you the way whereby ye may lay hold on every good thing.
22 For behold, God knowing all things, being from everlasting to everlasting, behold, he sent angels to minister unto the children of men, to make manifest concerning the coming of Christ; and in Christ there should come every good thing.
25 Wherefore, by the ministering of angels, and by every word which proceeded forth out of the mouth of God, men began to exercise faith in Christ; and thus by faith, they did lay hold upon every good thing; and thus it was until the coming of Christ.
27 Wherefore, my beloved brethren, have miracles ceased because Christ hath ascended into heaven, and hath sat down on the right hand of God, to claim of the Father his rights of mercy which he hath upon the children of men?
29 And because he hath done this, my beloved brethren, have miracles ceased? Behold I say unto you, Nay; neither have angels ceased to minister unto the children of men.
30 For behold, they are subject unto him, to minister according to the word of his command, showing themselves unto them of strong faith and a firm mind in every form of godliness.
36 Or have angels ceased to appear unto the children of men? Or has he withheld the power of the Holy Ghost from them? Or will he, so long as time shall last, or the earth shall stand, or there shall be one man upon the face thereof to be saved?
37 Behold I say unto you, Nay; for it is by faith that miracles are wrought; and it is by faith that angels appear and minister unto men; wherefore, if these things have ceased wo be unto the children of men, for it is because of unbelief, and all is vain.
