"Blessed are the merciful, for they will be shown mercy." (Matthew 5:7)
The sentiment of these words spoken by Jesus in what has become known as the "Sermon on the Mount" is as applicable today as it was then.
Paul writing to the church in Rome concerning the grace gifts of the Spirit says, "...if it is to show mercy, do it cheerfully." (Romans 12:8)
Mercy is the ability to detect hurt and empathize with those who are suffering. Thise with the gift of mercy have the ability to provide compassionate and cheerful support to those experiencing distress crisis or pain.
The account of the Good Samaritan (Luke 10:30-37) is a wonderful example of mercy in action.
