Why is the purpose of Jesus' death on the cross important for Christians?

The Scriptures are clear that Jesus, as the Good Shepherd, lays down His life for the sheep (John 10:11). His sacrificial death is not a general provision but a specific act intended to redeem His own people (Titus 2:14). The distinction is crucial; Christ did not die to make salvation possible for everyone but to accomplish the salvation of those chosen by God. This understanding reinforces the assurance of salvation for believers, knowing that Christ's death was effective and purposeful.
