>however, it is never explained as to how he waves a magic wand and fixes the many, many entirely man-made problems we have.
It's explained in the Book of Revelations - Jesus comes back and kills everyone who isn't Christian (and actually most Christians too) with plagues and fire and violence and burns the world down to ashes. And then (something something multi-headed dragon something something Whore of Babylon) a giant cube-shaped crystal city drops down from space lit by God's radiance and all of the dead Christians come back wearing white robes to live there and eat and drink and praise Jesus forever and never leave because why would you?
And belief in this is legitimately a big part of why we will never take climate change seriously.
>Jesus comes back and kills everyone who isn't Christian (and actually most Christians too)
I don't recall this part what's the reference
An overwhelming number of Christians do not believe this and do not interpret Revelation in this way. The belief that "Jesus will come back and solve everything instantly" is only held by a minority of small 2nd Great Awakening groups and a few outspoken Evangelical groups, and is unique to theological traditions that arose in the United States. The official teachings of the Catholic Church, Orthodox Churches, Anglican and Episcopal communions, Presbyterian denominations, etc and other mainline Christians don't believe this. Before you blame a group for ruining the world or rejecting climate change please actually talk to a representative sample of real people in the group you are making claims about.
