>>507531958jews don't believe in an after-life in heaven, they believe in resurrection on earth after intervention by their messiah, which is what Christians also believe but believe Jesus is the identity of the messiah.
Many Christians believe in heaven and an afterlife, determined by their merit and worthiness after judgement, and seek judgement.
The latter is a remnant of pagan belief structures, similar to warriors seeking a noble death in battle. Jesus even compares heaven to a mustard seed that will grow into a great tree... to Germanics that would have sounded a lot like a description of Yggdrasil.
