After Life

Which of the major monotheistic religions focusses most on the afterlife (akhira) and which is concerned with this life (dunya)?
All opinions welcomed.
Except being rude about other beliefs.

(as 2007 revival personality of the year i withold the right to ban you.)

i dont really know the akhirah/dunya point of view of Judaism.

but arent Christians also about the next life and confused. they are already going to heaven because Jesus ('alaihissalaam) died for them? but they should be grateful for this all their lives? (hence the people who arent grateful go to Hell?) is this how it works?

Is it true? Is it kind? Is it necessary?
