As I was reading Hebrews 10 last night, I came across a verse I’ve read many times, but thought I’d comment on. The verse is verse 14, which states, “For by a single offering he has perfected for all time those who are being sanctified.” In other words, by the single offering, blood atoning, propitiatory sacrifice of Christ, He has perfected (past tense, i.e. it happened in history) for all time the very people who are being (present tense) sanctified (made holy). His sacrifice was not a potential sacrifice. His sacrifice accomplished something objectively, for certain people, namely those who are being sanctified now, i.e. believers. This work is something that has happened to them, not by their initiation per se, but by His own perfect, infinite power and work on the cross in particular, as stated here. His work accomplished the very perfecting necessary to bring people into heaven. However, not everyone is perfected. Therefore His sacrifice was made for particular persons, namely the remnant, chosen by His grace (Ephesians 1 expands upon this).
