If this world were meant to be totally destroyed and void of all life, it would have been done so long, long ago. God provided us with choice. He provided us with survival skills. And when choice was provided he gave man the opportunity to do the right thing or fall into the hands of the enemy. Which many have done. As bad as it has become, in the world that we live in today, as long as we have GOD there is no question that our spirit will remain intact. Those that find salvation in the word. Those that do not let the fires of the world destroy them. Those that remain in faith will most undoubtedly survive the the struggles. You see we do not have any insight to what God has planned for us. Believe it or not it is better that we don't know. We would ruin the plan.
Jeremiah 29:11“For I know the plans I have for you,” declares the LORD, “plans to
prosper you and not to harm you, plans to give you hope and a future.”
