How do we know that Christ's sacrifice was limited?

The doctrine of limited atonement asserts that Christ's death was specifically intended for the elect—those whom God predetermined to save. Scriptures like Matthew 1:21 affirm that Jesus came to save His people from their sins, while John 10:11 clarifies that He lays down His life for the sheep, not for all of humanity indiscriminately. Furthermore, understanding that God does all according to the counsel of His will (Ephesians 1:11) strengthens the argument that Christ's death was not a mere possibility for salvation for everyone, but a definite accomplishment for those God had chosen.
