Hebrews 9:28

Verse 28. So Christ was once offered. As men are to die but once, and as all beyond the grave is fixed by the judgment, so that his death there would make no change in the destiny, there was a propriety that he should die but once for sin. The argument is, there is one probation only, and therefore there was need of but one sacrifice, or of his dying but once. If death were to occur frequently in the existence of each individual, and if each intermediate period were a state of probation, then there might be a propriety that an atonement should be made with reference to each state.
