I could post LOTS to you - so far you've stomp on the Word of God with NO knowledge or belief of it and imply God is unfair. Yeah, sure you are a christian LOL!!! while showing your lack of knowledge and belief in the most basic.
"Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’"
The biggest disappointment Christians have is when they die, meet Jesus, and he tells them they have to reincarnate again, they will not be in heaven.
They do earn good merit for their faith, and Jesus will lead them to a situation where they can work off debts from previous lives, rather than just have faith alone.
Hopefully they will make good progress on their souls evolution to freedom from rebirth and reuniting with Christ.
