Climate change? War? Disease? Animal species extinction? Land scarcity? Overpopulation? Pollution? All these things are fear mongering lines that satan uses to cause humans to act with irrationality, hatred, hoarding, and fighting one another. I used to be part of this unbelieving hoard. These cause people to lose hope, lose faith in God, and act totally selfishly. The propagators of these viewpoints pass laws to control, and they conspire to spread unGodly propaganda to control populations, limit families, and control resources. Having been a tree-hugger of the highest order, loving animals more than people, and grieving constantly over the state of the world, I fought the wisdom of God UNTIL JESUS!! Understand, all of these concerns are real, and we are to be good stewards of our earth to the best of our comprehension and ability, BUT, when we believe on God and His Son Jesus, who came to redeem us from the consequences of sin (which are seen in our world), and we read and understand the truths in the Bible, our hearts will come into a glorious rest. Grab a Bible and read the last two chapters; Revelation 21 and 22. The last chapters of a book bring the conclusion, solution, or resolution of a problem. The truth will set you free!
