Jesus suffered pain and death because God decided that should be important in saving some sinners for reasons secret to Him that had nothing whatsoever to do with the sinner. Why did Jesus have to die? So those who turned to Him could live? Not according to proud self-described elect Christians. They think turning to Jesus of their own will is not possible, so Jesus died and God had to make them believe it was for the elect few but not for everyone. The special few will believe because God will force them to believe and the rest will be burned in hell for God's pleasure and glory.He tasted death for every man. The immediate context clarifies who the every man are in Heb 2:9-10
But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
10 “For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings. The suffering here culminates into His death in Vs 9
He tasted death for everyone of the many sons, that is supported by the immediate context.
I don't believe that "special few chosen to be loved by God from billions of sinners God predestined to burn in the fire for His own glory and pleasure" nonsense.
