It’s an excellent analogy. I commend you for admitting your failure to understand.
Unfortunately you think spirituality comes naturally. God help you. No child ever does not
have to learn from scratch. Jesus said we have to become like children to enter the Kingdom.
This is learning everything again, which clearly you want to ignore because you are so far above
this.
Let us go to James for our first big spiritual lesson
7 Submit yourselves, then, to God. Resist the devil, and he will flee from you.
8 Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded.
9
Grieve, mourn and wail. Change your laughter to mourning and your joy to gloom.
10 Humble yourselves before the Lord, and he will lift you up.
James 4
To approach God to any degree we need to know our standing. Arrogance comes when acceptability
is assumed.
19 You will say then, "Branches were broken off so that I could be grafted in."
20 Granted. But they were broken off because of unbelief, and you stand by faith.
Do not be arrogant, but be afraid.
21 For if God did not spare the natural branches, he will not spare you either.
Rom 11
These are words spoken to believers about their attitude to God.
So many have no clue what this means, which illustrates the common lack of spiritual reality.
