We know from the Bible that Jesus Christ is in the express image of the Father:
(New Testament | Hebrews 1:1 - 3)
1 GOD, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;
What is the person of the Father? It is, of course, the BODY of the Father. That being said we do know that Jesus is considered our Father in the fact that God the Father gave us to Him due to the atonement. We read this in the Bible:
(New Testament | Matthew 11:25 - 27)
25 ¶ At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
26 Even so, Father: for so it seemed good in thy sight.
27 All things are delivered unto me of my Father: and no man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son, and he to whomsoever the Son will reveal him.
(New Testament | John 17:24 - 26)
24 Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.
25 O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.
26 And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
There is also this:
(Book of Mormon | Mosiah 15:2 - 8)
2 And because he dwelleth in flesh he shall be called the Son of God, and having subjected the flesh to the will of the Father, being the Father and the Son—
3 The Father, because he was conceived by the power of God; and the Son, because of the flesh; thus becoming the Father and Son—
4 And they are one God, yea, the very Eternal Father of heaven and of earth.
5 And thus the flesh becoming subject to the Spirit, or the Son to the Father, being one God, suffereth temptation, and yieldeth not to the temptation, but suffereth himself to be mocked, and scourged, and cast out, and disowned by his people.
6 And after all this, after working many mighty miracles among the children of men, he shall be led, yea, even as Isaiah said, as a sheep before the shearer is dumb, so he opened not his mouth.
7 Yea, even so he shall be led, crucified, and slain, the flesh becoming subject even unto death, the will of the Son being swallowed up in the will of the Father.
8 And thus God breaketh the bands of death, having gained the victory over death; giving the Son power to make intercession for the children of men—
