Prophets and saints of all ages have seen the Lord, Jesus Christ. He is manifested in dreams in the night, visions during day, and face-to-face as with Moses and Joseph Smith. There are a few who have been honored to see the Father, however, seeing the personage of the Holy Ghost in another matter.
His presence is manifested, his influence is felt, his voice is heard, but his person is kept hidden from view except in rare instances[1]. Man’s attention is not intended for any being except the Father whom we worship, and the Son, through whom we worship.
