Why did Yah accept Able's offering and not Cain's? I believe it is because when one have sincere faith they will serve as Yah wants, rather than serving Yah as they want;
Genesis 4 WEB
“1, The man knew Eve his wife. She conceived, and gave birth to Cain, and said, “I have gotten a man with Yahweh’s help.
2, "Again she gave birth, to Cain’s brother Abel. Abel was a keeper of sheep, but Cain was a tiller of the ground.
3, "As time passed, it happened that Cain brought an offering to Yahweh from the fruit of the ground.
4, "Abel also brought some of the firstborn of his flock and of its fat. Yahweh respected Abel and his offering,
5, "but he didn’t respect Cain and his offering. Cain was very angry, and the expression on his face fell.
6, "Yahweh said to Cain, “Why are you angry? Why has the expression of your face fallen?
7, "If you do well, will it not be lifted up? If you don’t do well, sin crouches at the door. Its desire is for you, but you are to rule over it.”
They both did works, and one's works were accepted one's works were not accepted. The heart that truly loves Yah will do as Yah says.

Cain offered "from the fruit of the ground"
Abel "also brought some of the firstborn of his flock and of its fat" the word also there means he brought "firstborn of his flock and of its fat" and "fruit of the ground"
Now this shows us that offering "fruit of the ground" was not in iteself wrong, so what could be the difference?
Hebrews 11:4, “By belief, Heḇel offered to Yah a greater sacrifice offering than Qayin, through which he obtained witness that he was righteous, Yah witnessing of his gifts. And through it, having died, he still speaks.”
1 John 3:12, “Not as Qayin who was of the wicked one and killed his brother. And why did he kill him? Because his works were wicked but those of his brother were righteous.”
"By belief" and "works...of his brother (Abel) were righteous"
Why were they righteous? What is righteous?
Hebrews 11:6, “But without faith it is impossible to please Him, for he who comes to Yah has to believe that He is, and that He is a rewarder of those who earnestly seek Him.”
Deuteronomy 6:25, "And it is righteousness for us when we guard to do all this command before יהוה our Strength, as He has commanded us.”
Psalm 119:172, “My tongue sings of Your word, For all Your commands are righteousness.”
Exodus 20:6, "But showing love to thousands who love Me by keeping My Laws."
1 John 5:17, "All unrighteousness is sin, and there is a sin not unto death."
1 John 3:4, "Whoever commits sin, transgresses also the Law; for sin is the transgression of the Law."
Did not Cain do works, yet his were not accepted, while faithfil and righteous Abel's works were...Reminds me of this...
Mat 7:21-23, "Not everyone who says to Me; Teacher! Teacher! Will enter into the Kingdom of YHWH, but only he who does the will of My Father Who is in heaven. Many will say to Me in that day; Teacher! Teacher! Have we not prophesied in Your Name, and cast out demons in Your Name, and in Your Name performed many wonderful works? But then I will declare to them; I never knew you. Get away from Me, you who practice iniquity."
