The Apple is symbolic of the fruit nature offers unto humanity.

The Serpent is symbolic of the wisdom to be had by feeding upon the forbidden.

For if someone forbids you something, you can be certain they are keeping you from your maturation.

Keeping you In service and worship, and not your growth and ascension.

Be not restrained by another.

Explore everything and shun those presuming any authority over you, and keeping humanity ignorant.

Fear restricts, condemns, and oppresses.

But love affirms, encourages, and empowers.

The Abrahamics perpetuate the former, while the Adversary perpetuates the latter.
