God is Merciful

Luke tells us the very moment the tempestuous winds of Apostolic indignation increase, Divine rebuke says,
“Ye know not what manner of spirit ye are of.” Luke 9:55
The disciples wanted to see swift justice, but Jesus doesn’t care about their notion of justice. Jesus commands them, not to desire justice, but to pray for, bless, and do good to those who hate them (Mat 5:44). This very Jesus is the lens from which we interpret the Old Testament, because Jesus is the icon of the invisible God (Col 1:15). No man has seen God (Jhn 1:18), because to see God in all his mysterious abstract essence is to die (Exo 33:20). However, thanks to the incarnation, we can see God as tangibly revealed in Jesus Christ the Son (Jhn 14:9).
