Arminians, like Roman Catholics, think they have a hand in their salvation. Calvinists believe, as did the giants of the Reformation, that "Salvation is of the Lord."
It's a difference in perspective, and not a small one.
PROBABLY?????
What do yall have to do to be sure? Amazing! I would not have included the works with salvation and added accept but other than that no argument. If you have accepted Christ as your savior then you KNOW you are one of the "Elect". There is no probably to it.
