Biblical mercy is lovingkindness directed at the miserable — kindness that meets a creature where weakness, need, or guilt has put it. The Hebrew chesed covers covenant loyalty extended even when undeserved; the Greek eleos covers compassion stooping to the wounded. Christ’s ministry was a continual flow of such mercy: "I will have mercy, and not sacrifice" (Matthew 9:13; 12:7; quoting Hosea 6:6). Mercy is the recurring cry of those who would be saved: blind Bartimaeus (Mark 10:47-48), the ten lepers (Luke 17:13), the publican (Luke 18:13). Mercy is also a Christian duty: "Blessed are the merciful: for they shall obtain mercy" (Matthew 5:7). The merciful are children of the Father (Luke 6:36).
That benevolence, mildness, or tenderness of heart which disposes a person to overlook injuries, or to forbear punishment.
MERCY, n. That benevolence, mildness, or tenderness of heart which disposes a person to overlook injuries, or to treat an offender better than he deserves.
In Scripture, mercy is one of the great divine attributes; God is described as plenteous in mercy, and Christ's entire earthly ministry is described as a flow of healing, forgiving, and feeding mercies toward the helpless.
Hosea 6:6 — "For I desired mercy, and not sacrifice; and the knowledge of God more than burnt offerings."
Matthew 5:7 — "Blessed are the merciful: for they shall obtain mercy."
Luke 10:37 — "He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise."
James 2:13 — "He shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment."
Modern Christianity often pairs mercy with leniency only; Scripture pairs it with compassion that costs the helper to give it.
The Good Samaritan's mercy in Luke 10 cost him a donkey, a delay, and two pence. It was not vague good feeling; it was concrete help paid for. Mercy in Scripture always costs the merciful man something.
James 2:13 makes the symmetry sharp: he shall have judgment without mercy, that hath shewed no mercy. The merciful obtain mercy; the unmerciful do not. The household that practices mercy receives it.
Hebrew and Greek both have a word for the loving-kindness directed at the wretched.
Hebrew chesed — covenant loyalty, loving-kindness, mercy; one of the great Old Testament words for God's character.
Greek eleos — compassion, mercy; the New Testament's standard term.
"Mercy is concrete; it costs the merciful something."
"Blessed are the merciful, for they obtain mercy — the symmetry of James 2."
"I will have mercy, and not sacrifice — that ranks the priorities."
