What is the Good News of the New Testament about?
“I’ve said it once and I’ll say it again and again, because I need to be reminded myself: 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. Even now, the banner under which Christians live reads, “It is finished.” Everything we need, and everything we look for in things smaller than Jesus, is already ours in Christ.”
