Because he himself suffered when he was tempted, he is able to help those who are being tempted.
(Hebrews 2:18, New International Version)
Jesus was tempted like we are! He suffered like we do! God in his grace made sure that we have someone in heaven who knows what it is like to face suffering and mortality. This knowledge is not only omniscient wisdom. Jesus also guarantees that heaven's knowledge includes human experience. Aren't you thankful that Jesus knew suffering and mortality and that he now lives to redeem, to bless, and to ultimately help us mortals?
