Ask yourself, who shows more mercy and grace God or men? Answer is obvious, God does! Men spin up prisons while God set up cities of refuge for those who committed involuntary manslaughter. If God is more merciful, why do we appreciate Him less and give less attention to Him?
Deuteronomy 19:1-4
1 “When the LORD your God destroys the nations whose land he is giving you, you will take over their land and settle in their towns and homes.
2 Then you must set apart three cities of refuge in the land the LORD your God is giving you.
3 Survey the territory,a and divide the land the LORD your God is giving you into three districts, with one of these cities in each district. Then anyone who has killed someone can flee to one of the cities of refuge for safety.
4 “If someone kills another person unintentionally, without previous hostility, the slayer may flee to any of these cities to live in safety.
