G-d gifted us human beings with choice. This means G-d gave us two options or two possibilities. The choice for good or the choice for evil.
This choice is what makes us human beings.
G-d gave us a great mercy. G-d gave us the ability for light and dark. The light represents good while dark represents evil in the world.
This is purpose of creation is focused on one huge decision G-d gave us.
Do we make the right choice?
Do we choose good? Or do we choose evil?
I choose good.
