Latter-day Saints are nonplussed by those that say that God cannot be seen yet believe that Jesus is God, and why are they so puzzled? The answer is stunninly simple, "Because, Jesus could be, and was, seen!"
Therefore, if Jesus was seen, and if they insist he is God the Father, then God can be, and was, seen by men, women, and children. How then can any of them say that God cannot be seen?
Has anyone ever SEEN God? Scriptures such as John 1:18, Exodus 33:20, John 6:46 and 1 John 4:12 say no, but Bible passages such as Genesis 32:30, Exodus 33:11, Isaiah 6:1 and Job 42:5 appear to contradict them.
Someone asked: "How many Gods are there?"
According to non-Mormon site, biblestudy.org, there are two distinct Gods. They write:
“From the scriptures mentioned at the beginning of this answer and from many others we learn that the doctrine of monotheism (the belief there is literally only ONE God Being) normally associated with Judaism and the vast majority of Christianity is FLAWED.
“There are TWO beings Who are God: God, the Father and God, the Son.
“While it is true that God is "one" (Deuteronomy 6:4), the Hebrew word translated as "one" is echad, which is the same Hebrew word translated as "one" in Genesis 2:24, saying that a man and his wife shall become "one" flesh.
“God, the Son (Jesus/Yashua) was born and lived on this earth as a man, prayed to God, the Father and obeyed the will of God, the Father. Jesus / Yashua was cruelly murdered for no good reason, was resurrected and returned to His former station at the right hand of God, the Father and was given all authority in heaven and the earth. (Matthew 28:18, John 8)
“There only SEEMS to be an apparent contradiction in the scriptures you mentioned because most people do not understand that there are two Beings who are God.”
The question is asked: "Has anyone seen God the FATHER? Non-LDS site biblestudy.org answers thus:
"The below scriptures tells us that no one has seen God, the Father:
"For the law was given through Moses; grace and truth came through Jesus Christ. No one has ever seen God, [the Father] but God the One and Only, who is at the Father's side, [Jesus/Yashua] has made him known. " (John 1:17-18, NIV)
"No one has seen the Father except the one who is from God; only he has seen the Father. " (John 6:46, NIV)
"This is love: not that we loved God, [the Father] but that he loved us and sent his Son as an atoning sacrifice for our sins. Dear friends, since God so loved us, we also ought to love one another. No one has ever seen God [the Father]; but if we love one another, God lives in us and his love is made complete in us. We know that we live in him and he in us, because he has given us of his Spirit." (1 John 4:10-13, NIV)
It is confusing to Christians that read the Bible to understand why appearances of God the Father are ignored as if they were not in the Bible. For example, bible.org records:
Acts 7:54 When they heard these things, they became furious and ground their teeth at him.
7:55 But Stephen, full  of the Holy Spirit, looked intently  toward heaven and saw the glory of God, and Jesus standing  at the right hand of God. 7:56 “Look!” he said.  “I see the heavens opened, and the Son of Man standing at the right hand of God!”
7:57 But they covered their ears,  shouting out with a loud voice, and rushed at him with one intent. 7:58 When  they had driven him out of the city, they began to stone him,  and the witnesses laid their cloaks  at the feet of a young man named Saul. 7:59 They  continued to stone Stephen while he prayed, “Lord Jesus, receive my spirit!” 7:60 Then he fell  to his knees and cried out with a loud voice, “Lord, do not hold this sin against them!”  When 180 he had said this, he died. 181
This website provides the following Notes:
 Greek “being full,” but the participle ὑπάρχων has not been translated since it would be redundant in English.
 Greek “looking intently toward heaven, saw.” The participle ἀτενίσας" has been translated as a finite verb due to requirements of contemporary English style.
 The picture of Jesus standing (rather than seated) probably indicates his rising to receive his child. By announcing his vision, Stephen thoroughly offended his audience, who believed no one could share God’s place in heaven. The phrase is a variation on Psalm 110:1.
 Greek “And he said, ‘Look!’” Because of the length of the Greek sentence and the tendency of contemporary English style to use shorter sentences, καί has not been translated here; a new sentence is begun instead.
 They covered their ears to avoid hearing what they considered to be blasphemy.
 Greek “And when.” Because of the length of the Greek sentence and the tendency of contemporary English style to use shorter sentences, καί has not been translated here; a new sentence is begun instead.
 They began to stone him. The irony of the scene is that the people do exactly what the speech complains about in v. 52.
 Or “outer garments.” Laid their cloaks. The outer garment, or cloak, was taken off and laid aside to leave the arms free (in this case for throwing stones).
 Greek “And they.” Because of the length of the Greek sentence and the tendency of contemporary English style to use shorter sentences, καί has not been translated here; a new sentence is begun instead.
 Greek “Then falling to his knees he cried out.” The participle θείς has been translated as a finite verb due to requirements of contemporary English style.
 The remarks "Lord Jesus, receive my spirit and Lord, do not hold this sin against them" recall statements Jesus made on the cross (cf. Luke 23:34, 46).
We shall focus on Stephen's dying testimony that he saw God the Father and Jesus Christ standing together above him in the air. That testimony was:
"I see the heavens opened and the Son of Man  standing at the right hand of God!"
 Son of man is a Messianic title for Jesus Christ.
""What is man that you [God the Father] think of him or the Son of Man [Jesus] that you [God the Father] care for him?You [God the Father] made him [the Son of Man, Jesus] lower than the angels for a little while. You [God the Father]crowned him [the Son of Man] with glory and honor. You [God the Father] put all things under his [the Son of Man Jesus']control.”
Did Stephen really see God the Father? Remember, Stephen was filled with the Holy Ghost, so that what he was and what he declared were solid truths that cannot be explained away by sophistry or theological distortion. His declaration is simple and direct:
"I see the heavens opened
and Jesus Christ standing
at the right hand of God the Father!"
What more compelling evidence is required to believe that God the Father showed himself to the protomartyr in open vision as he died for his testimony of the Christ?
