I have talked with Christians on the socialist left who say we need to move on from abortion to be more concerned about social justice....
And also about size of the world, I told him God's command was to be fruitful and multiply, and fill the earth and subdue it... and he said we already did that. They really dont like the subdue and dominion part, they really dont.
But really, no, huge areas of the world have few or no people, not just deserts either.
26 Then God said, “Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth.” 27 So God created man in His own image; in the image of God He created him; male and female He created them. 28 Then God blessed them, and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth.”
Many people are deceived by Satan and dont agree with God on this. They want nature to not be subdued and view mankind as a parasite of 'mother earth'
