The Kingdom, Hurt People, And Paganism

This whole Kingdom of God concept is making me crazy.

1) Is it on heaven or on earth? Maybe both?
2) Is it eternal or for 1000 years?
3) Is it here now or is it still to come?
4) Is it literal or spiritual?

There are plenty of evidences in the bible to back up all of these, some have more support than others, but all can be supported. If it's here now and spiritual only, the hype is more than it deserved. If it's only 1000 years - the millenial reign of Christ - then afterward is when satan is released for a while and THEN "eternity" starts. Scripture mentions those outside the kingdom and those who refuse to keep the sabbaths and the feasts in those days who will not be allowed access to the city of God.

Last night, my grandbabies' mom brought them over and was telling me of her plans to make them neo-pagans. I don't even quite know what that is, but she plans to take them to some vernal equinox celebration. She made it clear that she wants to get fully involved in whatever way she can as a rebellion against the Mormon church and the people in it. Her defining church moment was going to church as a teen and being accosted by some woman demanding to know how a bastard like she is dared to come into a church! This young woman has made some very bad choices in her life and is being condemned severely for them. I realize part of her is angry that someone dares to call her sin "sin". But I can't help but wish she was being loved into making good choices for herself. She's very much a young woman desperate to be married, she seems to believe marriage will solve all her problems, I'm pretty sure the Mormon religion encourages that point of view because of some of the doctrine that teaches only married people are acceptable to God.
Now she's closely following the talk about the Mayan calendar and is frightened that everyone will be dead in four years. She doesn't want to die. She believes that all children under eight are allowed into the kingdom of heaven automatically and little A will be eight in those four years. She's hoping/praying that if it's all true, that it will be the end before her little girl is no longer automatically safe, the other littles are younger.
So many young people are messed up by life, all of us are I guess. The Father sent us the answer in Jesus. Maybe she's the one I can study with. She's desperate, overwhelmed, and in her own words ready to give up.
