What do you mean by "end this age"?
This age is only temporary until God's prophets, Jesus and us saints have been found in the flesh and spoke the necessary prophesies and the word to change things like the flood and the end of this age. I spoke the word last January to end this age so it won't be long from now when the earth goes into it's changes.
There's not enough room on this earth to hold all God's creation so it has to be changed to get rid of the mountains and oceans and make the polar caps as warm as the rest of the earth. So this means the earth's crust has to be melted with hot lava from deep within the earth.
The flood covered up most of the original cracks of the crust to start the buildup of pressure in the mantle layer of the earth. So we're sitting on a timebomb that's soon going to blow. This will destroy everything on earth but it's necessary to make paradise for us.
God created us as images of thoughts within him. His first creation was light energy so he could have his images created. This light energy is the Word of God and it's needed to take the thoughts of God and put them into action. This light energy was used to make all the atoms according to the information of our images. God didn't miss one atom in his perfect plans and if wasn't for his plans, nothing would exist.
Once we die, we remain in our living images but we can't experience life without a body so when we die, it will seem like seconds before we wake up in a new body. This time, our bodies won't have genetic sins to keep us from knowing who we are. God only did that during this age to keep everyone liars so his men could hear the spoken Word of truth. It's much easier to hear the truth when everyone else isn't.
All God'creation will end up in new bodies and live forever in paradise.
