How does the doctrine of universal atonement differ from particular redemption?

The doctrine of universal atonement posits that Christ's death made salvation possible for all humanity, essentially putting salvation in the hands of individual choice. In contrast, particular redemption asserts that Christ's sacrifice was specifically intended for the elect, whom He secured through His death. This distinction reflects God's sovereignty and justice; if salvation depends on human decisions, it diminishes the power of Christ's atonement and portrays God as ineffective in achieving His purposes. Passages such as John 17:9 clarify that Christ prayed not for the world but for those given to Him, illuminating the specific nature of His redemptive work.
