It will happen perhaps when some certain believers or leaders whom God has specially chosen lay prostrate before God asking that their lives be taken on the spiritual altars, if it might mean that the salvation of all humanity might be realized.
That amounts to a demonic approach. God will never permit this. No other human than Jesus of Nazareth, God Manifest In The Flesh, can alone satisfy The Father's standards of perfection of a sacrifice. He is the only Human able to declare the New Coven=ant in His Pure, Perfect Blood.
Jesus died once, for all and for all time(Heb. 10:10). He says to each individual, essentially, "Choose or choose not; there is no after-death reprieve."
Oh I don’t disagree with that and obviously David was not allowed or required to die in that same way. There was recorded only his expression of his willingness to die if it meant that that God would stay such a plague. He could even see the angel of the Lord with his arm outstretched.
In some ways the martyrdom of Stephen is closer to what I meant. He loved not his own life unto death so that the gospel might be preached and souls saved. There is a point where a willingness to “ go all in” in terms of passion and faith that God respects and will act upon at times. The boys Shadrach, Meschak, and Abednigo were willing to go all in and went into the fiery furnace but were saved from it.
I was speaking of a totally heartfelt brokenness before God, a willingness to be entirely unmade so that the souls of men might be saved! It is the only thing recorded in the Bible and in certain points is history that prompt massive moves of the Spirit! Jonah was humbled and broken though somewhat unwillingly on his part and Nineveh was saved for a generation or two as the entire city repented before God.(But no he wasn’t actually killed or made to self sacrifice in the way my previous posting might have been perceived to have been suggesting. He was disciplined though).
