The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs—heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.
Romans 8:16-17 ESV

If we are fellow heirs with Messiah, what basis could we ever have for expecting that we would not suffer? If he, being perfectly obedient and God himself, suffered persecution, surely we who are imperfect reflections of him will also suffer persecution, both from man and from Satan.

When Yeshua said that he would draw all men to himself when he is lifted up, he didn’t only mean that he would draw their attention, but that he is drawing them to become like him and to follow in his footsteps, even to being lifted up on a cross as he was.
