Mercy

In light of Resurrection Sunday coming I was thinking about mercy today.
Webster defines mercy as: compassion that holds off punishing even when justice demands it.
I read that God has safety lock on His wrath but a hair trigger on His mercy! I love that.
Michael W. Smith has a song that repeats:
Lord have mercy
Christ have mercy
Lord have mercy on ME

When Abel was killed by his brother it says that his blood cried out to God from the ground.
The cry:
Justice.
When Jesus was crucified his blood cried out from the ground, too.
The cry:
Mercy, Mercy.
Which do you want?
