were talking bout Isaiah

Isaiah 1:18

Come now, and let us reason together

Definition of Occam's razor

: a scientific and philosophical rule that entities should not be multiplied unnecessarily which is interpreted as requiring that the simplest of competing theories be preferred to the more complex or that explanations of unknown phenomena be sought first in terms of known quantities.

THIS:

"This unconditional election is essentially related to the rest of the TULIP doctrinal outline and hinges upon the supreme belief in the absolute sovereignty of God over the affairs of man. God unconditionally elects certain people even though they are sinful as an act of his saving grace apart from the shortcomings or will of man. Those chosen have done nothing to deserve this grace."

AND THAT:

Romans 8:29-30

For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.

Romans 8:33

Who shall bring a charge against God’s elect? It is God who justifies.

VS: A mistake.

"explanations of unknown phenomena be sought first in terms of known quantities"

I just gave you three "known qualities". How many does "It was a mistake have? Case closed. The only reason it all makes sense is because its the truth. Ignore at your own peril.
