God does NOT DEMAND that we love, honor, and obey him and repent for sinning against him. It's a choice.
It's called free will.
2 Nephi 2:27--Wherefore, men are free according to the flesh; and all
things are given them which are expedient unto man. And they are free
to choose liberty and eternal life, through the great Mediator of all
men, or to choose captivity and death, according to the captivity and
power of the devil; for he seeketh that all men might be miserable
like unto himself.
Your statement: Any that dare not give all that he greedily covets is punished quite severely. This shows the depth of his greed.
Cannot be farther then the truth because the truth is about love. He does not condemn or punish those who do not give to him. It's a choice. Stated in the above verse as well as the below verse.
1 John 3:16-19 — “This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers. If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him? Dear children, let us not love with words or tongue but with actions and in truth. This then is how we know that we belong to the truth, and how we set our hearts at rest in his presence ...”
A jealous God?
We do not read very far in the Bible before we hear God saying, “You shall not make for yourself an idol, or any likeness of what is in heaven above or on the earth beneath or in the water under the earth. You shall not worship them or serve them; for I, the LORD your God, am a jealous God” (Exodus 20:4-5)
The root idea in the Old Testament word jealous is to become intensely red. It seems to refer to the changing color of the face or the rising heat of the emotions which are associated with intense zeal or fervor over something dear to us. In fact, both the Old and New Testament words for jealousy are also translated “zeal.” Being jealous and being zealous are essentially the same thing in the Bible. God is zealous—eager about protecting what is precious to Him.
