Calvinism to me sounds like sinning and saying, “I must not be a chosen one.” Sinning doesn’t mean you’re not chosen, it means you’re not believing. Everyone has the same opportunity to believe Him as the next person. If we’re all simply chosen and not called, then that makes Christ is a minister of sin and an advocator of sin. And why would God chose to send Christ to save us if He Himself is not worthy? That would mean there’s no true Gospel then, simply an idea of a hope that the God we create accepts the parts of us we choose to accept.
(Ref: Romans 3)
