Praying, “Lord, have mercy!”

In Orthodox liturgical services, we constantly pray, “Lord, have mercy!”  In the Gospel, Jesus Himself never refuses to grant a request made to Him seeking mercy.  Paul N. Harrilchak comments on this foundational prayer of the Christian people:

Not a sentimental plea or cry for pity; rather, an acknowledgement of the Father’s lordship – his sovereignty, power and faithfulness – and of our own sinfulness. We ask the Father of mercies, 2 Cor. 1.3, to remember his covenant with us and deal with the needs of all, not in accordance with our sins but in accordance with his mercy, Heb. 8.8-12. (Something of the scriptural meaning of mercy – hesed in Hebrew – can be gleaned from the RSV rendering, steadfast love.)
