Gospel-centered sanctification will lead to lawlessness.
Wasn’t this the objection of the Catholic Church when Luther proclaimed justification through faith alone? They objected that if people were taught that they would be saved simply through faith, they would leave off the mass, almsgiving, prayers, confession, and all other good works and sacraments. To this we all object that the Gospel in justification does not keep us from doing what God commands, but all the more motivates us to do what God’s Word teaches. And why not so in sanctification as well as justification? If the recognition that I can offer God nothing that will gain me merit in my justification does not lead to lawlessness, then why should the same recognition in regard to my sanctification do the same? No one is looking to make grace abound because of sin, rather, we look to the Gospel as the powerhouse of sanctification. Being good and glorifying God does not result from my intense self-discipline. It is a result of the Gospel. The more I come to see His righteousness in my place, the more I will be motivated, no, find the power, to live out who I really am in Christ.
