I did not live in the days of our Savior; he has not come to me in person. I have not beheld him. His Father and he have not felt it necessary to grant me such a great blessing as this. But it is not necessary. I have felt his presence. I know that the Holy Spirit has enlightened my mind and revealed him unto me, so that I do love my Redeemer, I hope, and feel it is true, better than everything else in this life. I would not have it otherwise.

Joseph Fielding Smith was called as an apostle in 1910. The above was a letter to his son in 1948.
