Genesis 3

God has commanded both man and woman (Adam and Eve) not to eat fruits from the tree of knowledge nor from the tree of life.

The crafty serpent succeeds in tempting Eve to eat a fruit from the tree of knowledge and Adam falls into sin after Eve.
After eating a fruit from the tree of knowledge, both Adam and Eve's eyes are open.
The bible says the tree of knowledge is the tree of good and evil.
Adam and Eve become aware of their surroundings and their nakedness.

I'm trying to grasp this concept of tree of knowledge, of good and evil.

Genesis 3:22
And the Lord God said, "The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever."

Numerous questions filling up my head and mind... and answers that are beyond my knowledge and understanding:
1. What exactly does He mean by good and evil?
Often times, my friends and I said we don't know what is truly righteous and wrong.
Our concept of right and wrong is affected by the societal values and educations from this world.
Therefore, our notion of right and wrong, our judgement, is not pure, because we lack the ability to discern the true righteousness from the true wrong-doings.
I wish I have a better diction than this to describe my confused "understanding".
What I'm confused about is when God says, "The man has now become like one of us"...
To whom does he refer to as plural "us"? Jesus, angels, and Himself?
I think the key of that sentence is "like one of us".

The man has now become like one of us; the man has not become one of us -not quite.

I think the tree of knowledge, of good and evil, made us capable of reason.

reason. rationality. perhaps intelligence.
Still... all those things are not the truth.
Our reason, our rationals, our intelligence cannot possibly serve to give us the truth of life.
We are surrounded and corrupted by the worldly teachings and knowledge.
Even though we try to live by the Bible, we still fall short of His glory, because of our nature of sin.
A lot of times our reasons are clouded by impurity, straying us away from the truth.

The impurity in our hearts is what separates us from God's knowledge of good and evil;
reason why we have only become like one of His heavenly servants.

This can be discouraging and encouraging revelation:
it's discouraging that we are so impure; but it's encouraging because God did not forsaken us despite our sins.
We can be purified by the blood of Jesus, His cross, His promise, and His undying love for us all.

Our tendency to reason can be beneficial or poisonous.
It's poisonous, because it opens ways for us to stray away from the truth of life and to acquire more worldly knowledge that makes more sense and looks more appealing to us.
But it can be beneficial; only when we purely reason based on the truth God teaches us in the Bible.

Oh,
what an irony.
I've been reasoning the whole time.
I hope my reasoning on this post has been "beneficial" though.
I've been trying to gain understanding and wisdom from God and let Him take me through Genesis and what He wanted to say in it.

Tough but good stuff.
I've only finishes Genesis 3, and God has revealed so much already.
The infinite wonders of His work.
Let me be the witness to Your work, father.
So that I can testify to the world and share the grace
