What/who got cursed?

Although Adam is culpable for eating the fruit of the tree, Yahweh does not curse him directly. Yahweh curses rather the soil with an unconditional malediction and simultaneously links the harm to Adam: 'Cursed is the earth because of you’. Basically, Adam’s hardship in life is a secondary consequence of the principal curse targeting the soil.— Cursed Are You!, page 202

Yep. That's something I've been saying for years now. People are under the mistaken impression that God cursed Adam and therefore them. What that results in is a mad god who is out to get them if they don't do what he wants.

That is most assuredly not the God of the Bible! It is not the portrayal of Jesus that we see in the Gospels.

Now, don't go the opposite extreme and create a Santa Claus god. God is still righteous and holy, but he is first and foremost love. I like to tell people that the attributes of God include holiness and righteousness, but his essence is love.
