Calvinism is built on ignorance of scripture. It limits God.
It refuses to rightly divide the word of truth.
It takes away the hope of anyone who was not ‘chosen by God’ before the world began.
It is a damnable heresy. It takes the few times that God has intervened in the lives of certain people, and extrapolates that intervention out to everything that that ever existed. It does all of this by adding to and taking away from God’s Word.
It makes God the mastermind of evil, making that belief system an abomination.
