How do we know that particular redemption is true?

The truth of particular redemption is rooted in the biblical concept of God's sovereignty and His election. In John 11:51-52, it is made clear that Christ died for specific individuals—those whom the Father gave Him. This idea is further supported in Romans 9:6-8, which clarifies that not all physical descendants of Abraham are children of God, but only the children of promise. This distinction emphasizes that Christ's atoning work is not arbitrary or universal but specific to the elect. Additionally, passages like Ephesians 1:4-5 show that believers are chosen in Christ before the foundation of the world, underscoring the particularity of redemption.
