"Oh a Calvinist, never mind, yall abandoned grace a long time ago."
Grace includes all of the terms God requires of us in order to be reconciled to Him. What a ridiculous situation we would be in if God sent His very special Son to pay the price of our redemption and then did not tell us what to do in order to inherit that salvation. "And being made perfect, he became the author of eternal salvation unto all them that OBEY him." (Emp. mine.) BTW, you did not answer either question. "Let him that thinketh he standeth, take heed lest he fall."
