When God spoke to Samuel the first time in the temple in the last chapter..
He informed Samuel that due to the sins of the High Priest's family were so egregious in God's eyes that he would be sending out punishments to them.
And he told Samuel what would be their punishment..
These verses here are sharing the wrath of God toward.
God is not one who is going to allow us to sin without consequence.
He has rules, Laws and gives us directions to live by and just like any parent who gives directions to their child they expect that they aren't wasting their breath.
How much more GOD should expect that we will listen to him and do as he asks of us!
God knows when we sin..
God knows that there needs to be order in the home
Eli failed ...
What did he fail in doing?
DISCIPLINING and TRAINING his sons..
As priests they were so sinful that God had to judge not just them as individuals but the entire family!
Because They weren't taught how to be obedient, because they weren't taught to follow their fathers orders and directions.
They couldn't comprehend obeying God or his orders and his directions.
That is why God orders parents to direct and give obedience lessons to their children.
I will be honest as I sit here writing a host of things come to my mind as things I need to get off the computer and start training my sons in..
As I don't want this fate for my children..
God is the same yesterday today and forever more..
So if the "God" you are learning about in sunday school isn't this GOD... Then you might wanna read your bible and see what it is they are preaching..
Me personally.. I am going to go and start being more diligent about raising my sons to fear and reverence myself and God's laws.
