Apparently you're the one who doesn't believe the Bible. Or you do not know what it says. There is at this time a heavenly kingdom, and I will go there, soon, when I die. And then one day, at the end of this age, that kingdom will fill the whole recreated earth. Until those two things happen—I die, and the kingdom comes to earth—we are to set our hearts and minds on that kingdom in heaven and on what happens in that kingdom so it can happen here, now. What part of that do you not understand?
Colossians 3:1-3
1Therefore, since you have been raised with Christ, strive for the things above, where Christ is seated at the right hand of God.
2Set your minds on things above, not on earthly things.
3For you died, and your life is now hidden with Christ in God.
4When Christ, who is your
a life, appears, then you also will appear with Him in glory.
