OK, so the question is common. In any case, Wells article is helpful. Check it out as supplimental reading as I continue my series (obviously, there will be some overlap in our presentations). Wells and I may not agree on the interpretation of certain biblical passages, but we both come to the same conclusion:
Words like Redemption, Reconciliation and Propitiation, when applied to the death of Christ, show that His death was for His people and not for every person who ever lived. Does that seem threatening? It need not. What we all must remember is that everyone who puts His trust in Jesus Christ as Lord and Savior will be saved. No one will ever believe, only to find that there is no Atonement for him or her.
The death of Christ is as broad as the category of believer. Beyond that it would do no good anyway. If Christ died for those who will never believe, His death would not help them in any fashion. It would only add to their condemnation. But Christ died for all who would ever believe. They, and no others, receive the benefit of the death He died for them.
