Exhortation is not practicing righteousness.
The gift of exhortation is mentioned among the spiritual gifts listed in Romans 12:6-8.
Since we have gifts that differ according to the grace given to us, each of us is to exercise them accordingly: if prophecy, according to the proportion of his faith; if service, in his serving; or he who teaches, in his teaching; or he who exhorts, in his exhortation . . . (NASB Romans 12:6-8
The word “exhortation” comes from the Greek word PAPAKALEO which means to ” appeal to, urge, exhort, or to encourage” someone to take a certain action. If we try to motivate someone to be kind to another person, we are exhorting him or her to action. Exhortation is something that pastors, teachers, and at times every Christian should do.
We are exhorted to honor God with our bodies.
