It’s time to open your eyes to the freeing power of authentic grace—grace that releases us from trying to earn God's favor, grace that enables us to rest in the finished work of Christ, grace that liberates from the tyranny of trying to please others. That's what the theology of Martin Luther and John Calvin did in their own day for the people around them. Time magazine recently dubbed Calvinism as one of the top ten ideas changing the world right now. And yet most of these discussions center on the issue of predestination or on whether particular people agree with the five points of Calvinism. Daniel Montgomery and Timothy Paul Jones think it's time to rescue the theology of the Reformers from such stale scholasticizing and to declare anew the dangerous and intoxicating joy of the gospel that theyproclaimed. PROOF stands for planned grace, resurrecting grace, outrageous grace, overcoming grace, and forever grace. The authors offer proof of God’s grace upon which people can stand against the attacks of legalism that have led many of God's people to lose sight of the freedom and joy of the gospel. And this proof is intoxicating—it’s like a 200-proof drink that will leave you spiritually staggering at its effect on your life. God’s grace not only declares us “not guilty!” in his presence, it changes our relationship with God—forever.?
