Cain's action

[Abigail]

Genesis 4:6 So the Lord said to Cain, “Why are you angry? And why has your countenance fallen? 7 If you do well, will you not be accepted? And if you do not do well, sin lies at the door. And its desire is for you, but you should rule over it.”


Concerning this scripture about how God is warning Cain about his anger and how sin (temptation) is lying at his door and that Cain should rule over the sin. Cain  doesn't and kills his brother Abel.


Is this murder an example of God's will or is an example of His permissive will?


Is resisting the sin God's will but Cain transgressed God's will?


The main question then, is God's will "always" followed?


Would value input because just this past weekend I was reading some posts (elsewhere), where the focus of the discussion is that, "ALL IS" God's ordained will.

 

I consider what God tells us in his inspired word.
Acts 4,
1stPeter chapter 1
2nd Timothy 1

Proverbs 16:9 A man's heart deviseth his way: but the Lord directeth his steps 
aka/ "Man proposes, God disposes"
"The dice are thrown in the lap, and every decision is from the Lord"   Proverbs 16:33
God has predestined all things according to his will, purpose, and divine plan. And for his glory.

And consider how much of the Bible is prophecy. Prophecy is informing us of God's predetermined plan of events to come.
Revelation being the biggest book to indicate that.
