How do we know particular redemption is true?

The doctrine of particular redemption is affirmed through the entirety of God’s redemptive plan as revealed in Scripture. It discusses the necessity of Christ's vicarious atonement for the elect, contrasting it with Arminian views of a general atonement. Key passages, such as Hebrews 9:28, teach that Christ was offered to bear the sins of many, and Isaiah 53:6 states that the Lord laid the iniquity of us all upon Him. This means that Christ’s death had a specific target in mind: the elect. As believers, we trust the promises of Scripture that assure us of the efficacy of the atonement for those chosen by God, affirming that salvation is assured for the elect based on the purposeful nature of Christ's sacrifice.
