A Short Study of Isaiah 32:17
“And the work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever.”
The work of righteousness is the work of Christ, not the work(s) of men. How could we have peace and a settled mind for assurance based upon our works? This would only be self-righteousness. But looking to and depending upon Christ for all righteousness, there is no greater peace and no better assurance to quieten our troubled spirits.
