Not P but DFW on Dostoevsky

[Mike Jing]

The following excerpt is from David Foster Wallace's Joseph Frank's
Dostoevsky:

Even if we suppose he was divine — did he know? Did he know he could have
broken the cross with just a word? Did he know in advance that death would
just be temporary (because I bet I could climb up there, too, if I knew
that an eternity of right-hand bliss lay on the other side of six hours of
pain)?

Here he is talking about Jesus Christ. What does the word "right-hand" mean
in "right-hand bliss"?
