God wills that all mankind shall be saved, (1 Timothy 2:4)
The Scriptural declaration in 1 Timothy 2:4 that God wills both the salvation of all mankind and the realization of the truth for all is a difficult one for those who think there will be an eternal hell.
This is especially so of those who recognize along with Augustine and Calvin that God?s will is being carried out in certainty.
This is the dilemma: If God has determined that only a certain number of people who are chosen by God beforehand will ever be saved and come to appreciate God's glory, how can it be said that He wills the salvation of all?
Augustine's explanation was that the word "all" here should be understood as all sorts of people and therefore seen as referring only to those who are predestined to believe in this life.
God wills that all mankind be saved (http://saviourofall.org/Writings/godwillsallsaved.html)
1 Timothy 2:4
... who desires ALL people to be saved and come to full knowledge of [the] truth.
It's an active, ongoing result of a previous action. And in the ongoing result of that action; desires (wants, wills) ALL men to be saved and come to the knowledge of truth.
The action is indicative. Nowhere is it subjunctive, or that of being contingent or probable, nor imperative on the subject?s response.
Neither is it optative, as in being unlikely or wishful thinking that mankind might come to this salvation and knowledge.
The koine is quite precise regarding the will of our God.
"He "willeth" = thelō =
To will, have in mind, intend. To be resolved or determined/ to purpose. His delight and pleasure to save the radical all of pas.
NOTE
Strengthened from the alternate form of haireō to determine (as an active option from subjective impulse).
