jesus lives?a question for christians

[gomp]

so jesus is alive in heavan

and some how him going to heavan(a really nice place) makes up for "sin"

what was giveing up in order to make this a sacrafice at all let alone the "ultimate" sacrafice?

because as far as the deffanition of sacrafice this doesnt cut it.

jsut thought I should point out how the central part of your religion is flawed and irrational
