What do we need to know about God?

What do we absolutely need to know about God?  Joseph Smith said

1. He is Eternal
“First, that he was God before the world was created, and the same God that he was after it was created.

2. He is Merciful
“Secondly, that he is merciful and gracious, slow to anger, abundant in goodness, and that he was so from everlasting, and will be to everlasting.

3. He is Unchangeable
“Thirdly, that he changes not, neither is there variableness with him; but that he is the same from everlasting to everlasting, being the same yesterday, to-day, and for ever; and his course is one eternal round, without variation.

4. He is Truthful
“Fourthly, that he is a God of truth and cannot lie.

5. He is No Respecter of Persons
“Fifthly, that he is no respecter of persons: but in every nation he that fears God and works righteousness is accepted of him.

6. He is Loving
“Sixthly, that he is love” (Lectures on Faith)

We can learn about Heavenly Father by learning about Jesus.

“Most scriptures that speak of God or of the Lord do not even bother to distinguish the Father from the Son, simply because it doesn’t make any difference which God is involved. They are one. The words or deeds of either of them would be the words and deeds of the other in the same circumstance. Further, if a revelation comes from, or by the power of the Holy Ghost, ordinarily the words will be those of the Son, though what the Son says will be what the Father would say, and the words may thus be considered as the Father's." (Bruce R. McConkie) 1982

2 Nephi 26:23-33 is a wonderful summary of His love and concern for the human family.

23 For behold, my beloved brethren, I say unto you that the Lord God worketh not in darkness.
24 He doeth not anything save it be for the benefit of the world; for he loveth the world, even that he layeth down his own life that he may draw all men unto him. Wherefore, he commandeth none that they shall not partake of his salvation.
25 Behold, doth he cry unto any, saying: Depart from me? Behold, I say unto you, Nay; but he saith: Come unto me all ye ends of the earth, buy milk and honey, without money and without price.
26 Behold, hath he commanded any that they should depart out of the synagogues, or out of the houses of worship? Behold, I say unto you, Nay.
27 Hath he commanded any that they should not partake of his salvation? Behold I say unto you, Nay; but he hath given it free for all men; and he hath commanded his people that they should persuade all men to repentance.
28 Behold, hath the Lord commanded any that they should not partake of his goodness? Behold I say unto you, Nay; but all men are privileged the one like unto the other, and none are forbidden.
29 He commandeth that there shall be no priestcrafts; for, behold, priestcrafts are that men preach and set themselves up for a light unto the world, that they may get gain and praise of the world; but they seek not the welfare of Zion.
30 Behold, the Lord hath forbidden this thing; wherefore, the Lord God hath given a commandment that all men should have charity, which charity is love. And except they should have charity they were nothing. Wherefore, if they should have charity they would not suffer the laborer in Zion to perish.
31But the laborer in Zion shall labor for Zion; for if they labor for money they shall perish.
32And again, the Lord God hath commanded that men should not murder; that they should not lie; that they should not steal; that they should not take the name of the Lord their God in vain; that they should not envy; that they should not have malice; that they should not contend one with another; that they should not commit whoredoms; and that they should do none of these things; for whoso doeth them shall perish.
33For none of these iniquities come of the Lord; for he doeth that which is good among the children of men; and he doeth nothing save it be plain unto the children of men; and he inviteth them allto come unto him and partake of his goodness; and he denieth none that come unto him, black and white, bond and free, male and female; and he remembereth the heathen; and all are alike unto God, both Jew and Gentile.
