What Is Mercy?
God's compassionate kindness toward those who deserve judgment, choosing not to give people what their wrongdoing has earned.
Meaning
Mercy in the Hebrew Bible often translates chesed, God's steadfast, covenant-keeping love, or rachamim, a word related to the womb, suggesting deep, parental compassion. In the Greek New Testament, eleos carries the same weight, most familiar from the repeated prayer Kyrie eleison, Lord, have mercy, used across centuries of Christian worship.
Theologians commonly distinguish mercy from grace this way, mercy is God withholding the punishment sin deserves, while grace is God giving favor and blessing that sin never earned. Ephesians 2:4 pairs the two, describing God as rich in mercy because of his great love. Jesus' parables, the prodigal son welcomed home, the unforgiving servant confronted for refusing to extend what he received, repeatedly dramatize mercy in action, and the Beatitudes pronounce a blessing on the merciful.
Mercy holds a especially prominent place in some traditions' devotional life. Eastern Orthodox worship repeats Lord, have mercy so often it functions almost as a heartbeat of the liturgy. Catholic devotion to Divine Mercy, associated with the twentieth-century visions of Faustina Kowalska, gave the theme fresh popular expression. Protestant traditions emphasize mercy as flowing directly from the cross, the clearest demonstration that God does not deal with sinners as their sins deserve.
In Scripture
Ephesians 2:4“But God, being rich in mercy, for his great love with which he loved us,”

Mercy: Frequently Asked
What is the difference between mercy and grace?
Mercy is God withholding the punishment sin deserves, sparing someone from judgment. Grace is God giving favor and blessing that a person never earned in the first place. The two are closely related and often appear together in Scripture, but they describe different sides of God's kindness.
Why do some churches repeat 'Lord, have mercy' so often?
This phrase, Kyrie eleison in Greek, is central to Eastern Orthodox and some Catholic liturgy, repeated as a recurring prayer throughout worship. It reflects the belief that human dependence on God's mercy is constant, not a one-time need, so the prayer for it recurs continually.
Is mercy something people earn through good behavior?
No. Christian teaching describes mercy as freely given by God, not a reward for good conduct. Scripture does call believers to extend mercy to others as they have received it, most vividly in Jesus' parable of the unforgiving servant, but mercy itself flows from God's character, not human merit.
