Read the Bible indiscriminately and you’ll get a mixed message. You’ll take on board commandments that were never meant for you and you’ll end up confused and lukewarm. You’ll fall from grace and into works. The way to avoid this is to read the entire Bible through the lens of Jesus and His finished work. When the Galatians fell into error Paul reminded them that “before your very eyes Jesus Christ was clearly portrayed as crucified” (Ga 3:1). A clear revelation of the cross is the best protection against falling from grace.
The cross changed everything. Prior to the cross everything pointed forward to Jesus and His redemptive work. Everything after the cross celebrates His finished work and invites you to rest.
