What does the Bible say about Christ's death and salvation?

According to Scripture, Christ's death was not a mere potentiality for all people but a definitive act for a specific group, the elect. For instance, 2 Corinthians 5:21 states that Christ was made sin for us, affirming that He suffered and died in the stead of sinners. The idea that Christ would suffer for those who are ultimately not saved contradicts the justice of God, implying a double punishment for sin. Therefore, the biblical evidence supports the view that Christ bore the sins of the elect, securing their salvation rather than making it possible for all without distinction.
