Proof stands for planned grace, resurrecting grace, outrageous grace, overcoming grace, and forever grace. The authors offer proof of God's grace on which people can stand against the attacks of cheap grace and 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.
