A good parent is concerned for the welfare of their child unconditionally. The State ought to be concerned, ultimately, for the welfare of all citizens without compromise.
The State, in modern western countries, is quite willing to strike Faustian bargains - euphemistically called ‘social contracts.’ It no longer concerns itself with the welfare of citizens that it determines have no political influence. Ergo, the wealthy, the loud, the socially influential, the powerful, the esteemed all have influence and the State binds itself, contractually, to them and to them alone. The weak, the voiceless, the forgotten, are of no concern to the State. This is why abortion and ‘assisted death’ are big on the political agenda in modern western countries. Those in jeopardy of forfeiting their lives do not count as far as the State is concerned – they don’t exist. They aren’t even loved conditionally. Their welfare is of NO concern to the State.
Jesus was clear that these ‘little ones’ are the ones who do count as far as God is concerned. He has shared their suffering with them and they will share his glory with him. In the Kingdom of Heaven they will find unconditional love. In the meantime, those who eke out, through their power and influence, their ‘reward’ on Earth have received all that they will be owed. In Jesus’ words, “They have received their reward.”
You say, “It has never been the job of the State to love citizens unconditionally.” Actually, it has been the duty of States to do so, but they have almost universally failed. You can excuse that failure if you wish and, by doing so, render to Caesar his duly owed apologia, but let’s not confuse failure with responsibility as if the State shouldn’t be held accountable for its abominations.
