If an angel comes in here and says, “Wait a minute. You can’t get to heaven by trusting Christ and Christ alone, and having the imputation of His merit. And the angel came here and said, “For you to really be justified you have to have inherent righteousness. You have to add works to faith, merit to grace, you to Christ.” If an angel from heaven came in here and said that this afternoon, I would take him by the seat of his celestial pants and kick him out of here!
