Since Christians are by definition followers of Jesus Christ, I often wondered why the vast majority never considered his words at the sermon on the mount: Matthew 5:5 - "The meek will inherit the earth."
Or Psalm 37:9,11, & 29 which Jesus was clearly alluding to.
Revelation 21:3,4 relates what the conditions on earth will be for humans.
People being taught that they immediately "go to heaven when they die" also confounds what Jesus said about his resurrecting people "on the last day."
If deceased people are in heaven watching their loved ones on earth suffering all sorts of terrible trials and tribulations for years, would you call that "heaven?" Just my thoughts.
