How do we know God's exclusive purpose of atonement is true?

The biblical teaching on atonement clearly distinguishes between the elect and the non-elect. Ephesians 1:4-5 emphasizes that God chose certain individuals for salvation before the foundation of the world, highlighting His sovereign initiative in redemptive history. This exclusivity is echoed throughout the New Testament, where Christ's death is portrayed as purposeful and effectual for those whom the Father has given Him.

The argument against hypothetical universalism rests on the principle of God's justice and the weight of His grace in the plan of salvation. If God were to intend salvation for all, it would create grave questions about His justice, leading to a misunderstanding of His character. Believers can trust in the steadfastness of God's promises, knowing that His grace operates specifically and effectually among His chosen people, ensuring their salvation as a reflection of His immutability and ultimate purpose.
