Why would you want to change the world for the better, when you believe that the answer to the problem is for things to get progressively WORSE...so that you can be "raptured"...once God finally gives up on His "Project Earth Failure"?
Bad Eschatology has done far more collective harm to our youth than guns, and is no doubt a contributing factor to much despair, hopelessness, low self-esteem, low self-worth, depression, anger, violence, death, ministry burnout, and ministries aborted...due to many novices attempting to "fulfill their call" before the imminent rapture buzzer sounds.
People greatly err when they confuse THOSE last days (Of the old system...ending in 70 A.D.) with this NEW DAY... and the Old Age, before the cross, with the New Age that was ushered in at the cross.
We'd also do well to stop conflating ancient metaphors that were fulfilled in and prior to 70 A.D. with present and futuristic reasons for a hopeless Earth that needs to be destroyed.
Our Loving Father has great things for this generation, while much of the church has "Left (Jesus' Gospel of the Kingdom) Behind" in favor of the modern-day Christian fiction of Darby, Larkin, Scofield, Lindsey, Van Impe, LaHaye, Hagee, and friends.
Was your response to the recent school shootings, "Father, what do you want to do through me to help change this?" or was it "That's just a sign of the times. We don't have much longer."?
Thy Kingdom come, Thy Will be done, on EARTH as it is in heaven!
The last time that I checked, there were no shootings in heaven; and there won't be any in God's fully renewed earth.
Apocalyptic, eschatological views (such as Dispensationalist Christian beliefs and Radical Islam) which look for ever-increasing war and destruction are incompatible with God's Kingdom Message of Love's ever-increasing rule and PEACE!
Mixing that error and worldview with politics conflates God's Will with a morbid expectation of ever-increasing evil, death, different brands of "Jihad" and the ultimate destruction of planet Earth...along with an overwhelming majority of its inhabitants. This is very sick and twisted stuff from the Gates (wisdom) of hell (Hades- which literally means "to not see")...which Jesus said would NOT prevail against His Church. It ultimately WON'T!
An ignorance of History (especially of the events surrounding 70 A.D. and the writings of Josephus) has lead so many well-meaning, professing Christians to a worldview that is in direct opposition to God's Will. You can't take specific warnings about the destruction of Jerusalem in 70 A.D. (along with specific, corresponding instructions) and apply them literally to the present or the future any more than you should be warning people about the imminent threat that dead Roman Emperors are to the world today!
Much of what we see in the world today isn't fulfilled, Biblical prophecy, it's just the self-fulfilled "prophecy" of religious mindsets which are in great need of being renewed through His Spirit, His Word, and a good History lesson!
Strongholds in the collective mind of the Church are greatly responsible for much of our bad history...which has repeated itself over and over.
Nevertheless, the prophet's words still ring true!
Isaiah 9:7 "There will be no end to the increase of His government or of PEACE, On the throne of David and over his kingdom, to establish it and to uphold it with justice and righteousness from then on and forevermore. The zeal of the Lord of hosts will accomplish this."
Ephesians 3:21 "unto Him be glory in the church by Christ Jesus throughout all ages, world without end. Amen."
Matthew 5:5 "Blessed are the meek: for they shall inherit the earth."
Ecclesiastes 1:4 "One generation goes and another generation comes, But the earth remains forever."
Your Kingdom come, Your Will be done, on EARTH as it is in heaven!
