“For it was fitting that He, for whom and by whom all things exist, in bringing many sons to glory, should make the Founder of their salvation Perfect through Suffering.” (Hebrews 2:10)

Even “He” subjects Himself to “Suffering” (the most painful one, silently) though He has “no sin”.

We suffer due to the evil which we have done or the evil done by others toward us; “not” because of God, since it’s written that, “God cannot be tempted by evil”.

So, who to “blame” for “suffering”?
Our sinful acts or of others including the so called “gods-princes of this age” in the “heavenly realms” (spirit world) who have “deceived” you & brought “evil” upon you as you’ve “declared them as your god”.
