Christianity is not first and foremost about our behavior, our obedience, our response, and our daily victory over sin. It is first and foremost about Jesus! It is about His person; His substitutionary work; His incarnation, life, death resurrection, ascension and promised return. We are justified – and sanctified – by grace alone through faith alone in the finished work of Christ alone.
