Satan says, "You need to do something to get what you need."
Jesus says, "You only need me. I will provide everything for you."
In the Hebrew language good is that which is functional & evil is that which is dysfunctional. The original lie to get us to taste evil was "If you know good & evil it will benefit you." Truth is good because truth works, truth is reality. Falsehood is evil because it does not work because it is not real thus it is harmful. You only need to live in reality.
Evil shatters our world when it says, "No no, this does work. You are the problem. If you do this or if you try harder at doing what you are already doing you can make it work. You can make this functional." Thus we spin our wheels trying to operate in that which was never meant to work, trying to make evil good.
We also do this in how we handle the knowledge of good & evil. We believe the lie that says, "I should always be judging between good & evil. It is best for me to apply my knowledge of good & evil in everything with everyone. Doing so will make me more like God. Knowing evil won't kill me, it will make me stronger."
You see Satan's lie to Eve was the very same lie religion uses, "knowledge of evil is good for you." What does knowledge of evil create? Sin consciousness & self-judgment. Adam & Eve were ashamed & hid from God when they knew evil. They began to evaluate themselves & with that came fear & shame & insecurity. BUT we were designed to live off of God's evaluation of us, TO LIVE BY THE FATHER'S LOVE FOR US.
But the ultimate damage of the knowledge of evil was not that it entices us into dysfunctional behaviors & beliefs that put the blame of their deficiency upon us. The ultimate damage of the knowledge of evil was that it can blind us to God's abundance, His abundant love for us.
The lie of Satan is, "You are deficient, you are evil but you can make yourself better by doing certain things."
The truth of Jesus is, "I love you but you are dying. Trust me & I will give you my life & we can live forever, together."
