Mercy very much can denote an attitude of compassion that reaches out to people who are suffering and hurting. Blind men followed Jesus and cried out for mercy. He healed them. A Canaanite woman sought mercy for her demonized daughter and Jesus delivered her. Likewise a father pleaded for mercy for his troubled son, and Jesus restored him.
Mercy can also carry a narrower meaning akin to forgiving someone. We see that meaning in the parable Jesus tells about the servant whom was forgiven a large debt by his master, but then refused to forgive the small debt he was owed by another servant. The master in the parable says these words to the unforgiving servant,
Mt 18:32 …‘You wicked servant! I forgave you all that debt because you pleaded with me. 33 And should not you have had mercy on your fellow servant, as I had mercy on you?’
The Message in translating this beatitude does a good job in capturing the scope of this word. It reads,
Mt 5:7a “You’re blessed when you care…”
The blessing associated with being merciful is that one will receive mercy. God will bless them by extending to them mercy. God will bless them by being compassionate to them and granting them forgiveness.
It is not that by showing mercy to others I cause God to show mercy to me. Rather my showing mercy to others is the occasion that demonstrates that I have received mercy from God. Or as the Message puts it,
Mt 5:7b “At the moment of being ‘care-ful,’ you find yourselves cared for.”
Recent economic news may have us tightening our belts, but mercy is something we can still afford to give this Christmas. In fact I don’t think we can afford not to give it.
