"You have been indebted to other men, in the first instance, for evidence; on that you have acted; but it is necessary that you receive a testimony from heaven for yourselves; so that you can bear testimony to the truth of the Book of Mormon, and that you have seen the face of God. That is more than the testimony of an angel. When the proper time arrives, you shall be able to bear this testimony to the world. When you bear testimony that you have seen God, this testimony God will never suffer to fall, but will bear you out; although many will not give heed, yet others will. You will therefore see the necessity of getting this testimony from heaven.
"Never cease striving until you have seen God face to face. Strengthen your faith; cast off you doubts, your sins, and all your unbelief; and nothing can prevent you from coming to God. Your ordination is not full and complete till God has laid His hand upon you. We require as much to qualify us as did those who have gone before us; God is the same. If the Savior in former days laid His hands upon His disciples, why not in latter days?" (Oliver Cowdery, HC v 2, ch 13, p 195)
