D&C 7:1-3, 7-8; “And the Lord said unto me: John, my beloved, what desirest thou? For if you shall ask what you will, it shall be granted unto you. And I said unto him: Lord, give unto me power over death, that I may live and bring souls unto thee. And the Lord said unto me: Verily, verily, I say unto thee, because thou desirest this thou shalt tarry until I come in my glory…And I will make thee to minister for him and for thy brother James; and unto you three I will give this power and the keys of this ministry until I come. Verily I say unto you, ye shall both have according to your desires, for ye both joy in that which ye have desired.”
John 21:20-23; “Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? 21 Peter seeing him saith to Jesus, Lord, and what shall this man do? 22 Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me. 23 Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee?” (Also see Foxe’s Book of Martyrs for listing of how each of these apostles died.)
Question: when and where did this conversation between Jesus and the apostle take place that’s been recorded in the Doctrine and Covenants?
