What does the Bible say about Jesus dying for everyone?

Scripture highlights that Jesus' sacrificial death was intended for a particular people, chosen by God before the foundation of the world. Jesus states in John 10:14-15, 'I am the good shepherd; and I know my sheep, and am known of mine,' indicating that He died specifically for those whom the Father has given Him. This is consistent with Hebrews 9:28, which asserts that Christ was offered once to bear the sins of many. Importantly, the notion that Christ's death provides salvation for all can only be true if one either believes that all men will ultimately be saved or that Christ's sacrifice merely makes salvation a possibility without securing it. However, both interpretations contradict the clear teaching of Scripture regarding the atonement's definitive purpose and effect.
