Romans 8:16-17

The Ruach Hakodesh himself bears eidus (witness) with our ruach that we are bnei HaElohim. And if bnei HaElohim, then also yoreshim (heirs) of G-d and co-heirs together with Moshiach, provided that we suffer with him in order that we might also be set in kavod (glory, eschatological glorification) with him.
