There is nothing you or I could do here - cure cancer, live a life of peace and love and joy, give money to the poor, read the Bible 4 hours everyday, or help the homeless, bereaved, or abused - that could make our lives here on this earth our own personal heaven. The idea that WE could make heaven what it is shocking to me that one would profess that.
The Bible says that no one knows what God has in store for those who love him. GOD will make the new heaven and the new earth what it will be and no one alive today could imagine it.
There is nothing you or I could do here - abort babies, sell drugs, abuse others, rob every bank in town, or deceive people out of their life's savings - that could make this place our own personal hell. We do not make hell, hell. God has prepared hell for the devil and his angels. Jesus said that humans will perish there, too.
No one alive today - even those who suffer more than we could understand - knows now the true sufferings of what hell will be for the lost.
God is in control of it all - both heaven and hell. Not us.
Actually, Jesus didn't say that, as I am about to show.
