How do we know that Christ's sacrifice is for the elect?

Throughout scripture, particularly in passages like Romans 8:28-30 and John 10:14-15, the focus is on Christ being the Good Shepherd who lays down His life for the sheep. This indicates that His sacrificial work is not a general offering for every individual but is specifically intended for those whom God has chosen. The doctrine of particular redemption teaches that Christ's atonement is effective and accomplishes salvation for the elect, ensuring that all for whom He died will ultimately be saved and will not face God's wrath, as they are justified and have their sins not imputed to them due to His sacrifice.
