Fifty Years from now you say? Well if the world continues on its preset rate of destruction there will not be any world then. However, thanks to God the Father he will not let this happen like He did in the time of Noah when only eight people survived because that world then was just as nasty to live in as it is now, Genesis 6:5, Matthew 24:37-39.
God has allowed us 6,000 years to bring peace on earth on our own terms but with Satan the Devil as our leader. Oh, yes Satan became human kinds leader in Genesis 3:1-24. Though God has very often revealed himself to us humans, we have more or less pushed God away from us in our attempt to bring peace on earth on own terms. So after all these centuries even after most rejected Jesus Christ they are no closer to peace then before. Now, the NWO and its elected world bankers and world leaders have come up with their great Eugenics plan to exterminate most of human kind with only 500 million chosen to live with the supreme author of destruction - Lucifer and his Luciferian plans, Revelation 12:9 - Check out the Georgia Guide Stones on your browser, we humans have a great plan to get rid of ourselves wholesale and cheap very soon within maybe the next ten years or shorter.
The question was how do I see the earth 50 years from now. Well, I see a brand new government run by the Saints of God under Jesus Christ, 1 Thessalonians 4:16 & 1 Corinthians 15:51-56, Revelation 20:1-4, 11-15.. This earth will become beautiful and there wil be no more war and pain, or death but happy humans with their Savior making the rest of the world ready for that great time when God the Father will come down and rule with us here and throughout the universe, Revelation 21 ( read whole chapter) 2 Corinthians 6:17-18. A new and better world is coming very soon because Jesus Christ will return and rescue us from ourselves and Satan's bloody leadership, Matthew 24:21-22, Revelation 22:12. This is God's promise to us, Genesis 9:8-17. Have you seen a Rainbow in the sky lately? Jesus is coming quickly, come Lord Jesus, Revelation 22:12-21. Amen!
