Why would a supernatural, all-powerful, all-knowing entity that created the entire universe want people to sacrifice animals for him? And what would he want with fruit and vegetables? And why did he decide to make Jesus die for man's sins? He could have easily just pardoned them, he's God, he makes the rules! And why did God even lie to Abraham making him think He wanted him to kill his own son?
The God of the Bible may not have been so evil as to torture bad humans for eternity in Hell, but He sure doesn't mind Him some sacrifices!
"Then Jeph´thah made a vow to Jehovah and said: “If you without fail give the sons of Am´mon into my hand, it must also occur that the one coming out, who comes out of the doors of my house to meet me when I return in peace from the sons of Am´mon, must also become Jehovah’s, and I must offer that one up as a burnt offering.” - Finally Jeph´thah came to Miz´pah to his home, and, look! his daughter coming out to meet him with tambourine playing and dancing! Now she was absolutely the only child. Besides her he had neither son nor daughter. And it came about that when he caught sight of her, he began to rip his garments and to say: “Alas, my daughter! You have indeed made me bend down, and you yourself have become the one I was ostracizing. And I—I have opened my mouth to Jehovah, and I am unable to turn back.” - "she made her return to her father, after which he carried out his vow that he had made toward her. As for her, she never had relations with a man."
"Please, here I have two daughters who have never had intercourse with a man. Please, let me bring them out to YOU. Then do to them as is good in YOUR eyes."
"Hence the man took hold of his concubine and brought her forth to them outside; and they began to have intercourse with her, and kept on abusing her all night long until the morning, after which they sent her off at the ascending of the dawn."
"Then he entered his house and took the slaughtering knife and laid hold of his concubine and cut her up according to her bones into twelve pieces and sent her into every territory of Israel."
"And [God] went on to say: “Take, please, your son, your only son whom you so love, Isaac, and make a trip to the land of Mo·ri´ah and there offer him up as a burnt offering on one of the mountains that I shall designate to you.” - And He went on to say: “Do not put out your hand against the boy and do not do anything at all to him, for now I do know that you are God-fearing in that you have not withheld your son, your only one, from me.” At that Abraham raised his eyes and looked and there, deep in the foreground, there was a ram caught by its horns in a thicket. So Abraham went and took the ram and offered it up for a burnt offering in place of his son"
"And Abel came to be a herder of sheep, but Cain became a cultivator of the ground. And it came about at the expiration of some time that Cain proceeded to bring some fruits of the ground as an offering to Jehovah. But as for Abel, he too brought some firstlings of his flock, even their fatty pieces."
