The two troubled sons in Jesus’ parable of the Prodigal Son didn’t understand grace either. (Yes, both sons were troubled.) Dr. David Orrison very simply spells it out. He writes:
“There are believers who do not seem to believe they are under grace. They continue to live according to the law. Their lives are built around standards and rules and principles and they struggle to feel good enough. Their hearts are often filled with work and resentment.
There are other believers who use the idea of grace to celebrate rebellion. They let themselves experience things that were forbidden under law and rejoice to feel no guilt. They push boundaries and standards to the side as they enjoy their new life apart from the law. But they sometimes find themselves in bondage to masters more cruel than the law ever was.”
