How do you know if you are chosen?
Caution, that is a devilish question! The devil stirs your curiosity up so that you want to fathom the secret of predestination. With that he wants to place humans above God and makes God suspect. Because when I want to know if I am chosen, I want to know what God knows and I want to be equal to Him, so that He does not know more than I. Then God is no longer God.
When you ask this question you shall eventually become impatient and finally you are going to hate God and curse Him.
