I appreciate Adrian Warkock’s understanding of the Antonment. He show a bery balanced view and how at the same time the atonement is applied in some way to everyone as well as specifically to only those that believe. His says
…we can surely agree that Jesus’ death was enough for the whole world, but will not be permanently applied to the whole world—so while unrepentant sinners do benefit temporarily from the death of Jesus, they will not benefit forever. It is only those who are united with Jesus that will ultimately benefit. Thus, to me the Scripture teaches that there is a sense in which Jesus died for the whole world, but another sense in which He died especially for those of us who are Christians.“. . . we have our hope set on the living God, who is the Saviour of all people, especially of those who believe.” (1 Timothy 4:10)
He goes on to Martin-Lloyd Jones on the benefits that come to the whole world from Jesus’ death:
“ . . . the only thing that made it possible for God to continue to have any dealings or any relationship with this world at all was the work that our Lord was going to do. So it was the cross, as it were, that spared the world and allowed it to continue. And in the same way, it is the cross and the cross alone that spares the life of anybody who ever sins at any time. It is only because of the work of the cross that God can even tolerate sin in any shape or in any sense.”
