ongoing peace of mind

"Without a gospel-centered approach to productivity, we can easily fall into a law-based approach to the Christian life that kills our joy and freedom...
...ongoing peace of mind comes through faith in Christ expressed in day-to-day life. This is the kind of peace that can endure even when everything is going haywire and we are simply unable to keep up with things. Why? Because it is not based on us. Just as we do good works from justification rather than for justification, we are also to do good works from peace rather than for peace"
