All that could have a thing to do with lack of understanding, lack of know how, lack of cooperation, lack of empathy, sympathy, and insistent need or lust for violence and to exert power and/or control over others.
But yeah, leave it up to God ... I'll agree in part. I choose to work hard, play harder, when I get my freak on I'll do it like a mean it, have fun, enjoy what i got today (may not be here tomorrow) and do what I can for others when I can without destroying my own well-being. It comes down to I know myself well enough to know and understand what I enjoy and what I don't, what's beneficial ... short or long term, and how to attain when I'm ready to attain. I'm an individual, so I can only speak for me. If I'm wrong ... so what? I enjoy my life best I'm able, help others when able, work hard the only way I really know how, and play even harder. God will sort us all out in the end, so ... I worry less, exercise a bit more faith than i once did, and live out loud or at least louder than before.
Yes, God will sort it out, Not any humans.
This will take place I find at the soon coming ' time of separation ' as mentioned at Matthew 25:31-33,37,40.
Not humans, but Jesus as Shepherd will separate the figurative humble 'sheep' from the 'haughty' goats.
The 'sheep' can remain alive on Earth and continue to live on Earth right into the start of calendar Day One of Jesus' coming 1,000-year governmental reign over Earth for a thousand years.
Besides hard work and playing harder, Jesus gave us the spiritual work found at Matthew 24:14; Acts 1:8 to tell the world about the good news of God's kingdom of Daniel 2:44, that God, through Jesus, will establish Peace on Earth among persons of goodwill.
