How do we know that Christ's atonement is limited to the elect?
Answered in 2 sources
Christ's atonement is specifically for His sheep, as stated in John 10:15, declaring He lays down His life for them, not for the whole world.
The doctrine of particular redemption holds that Christ’s atonement is intentionally directed toward the elect of God—those whom the Father has given to Him. In John 10:15, Jesus states, 'I lay down my life for the sheep,' indicating that His sacrificial death was meant to secure the salvation of His people specifically. Furthermore, John 17:9 reinforces this idea of particularity, as Jesus prays, 'I pray for them; I pray not for the world, but for them which thou hast given me.' This highlights that not everyone receives the same benefit from Christ's death—only those who are chosen and given to Him by the Father.
