What does John 3:16 mean in relation to Christ dying for some?

In the sermon, the preacher explains that John 3:16 ('For God so loved the world...') is often misinterpreted to support the idea of universal atonement. Instead, it highlights God's mercy extending to all nations, but the effective application of Christ’s atoning sacrifice is particular to those whom the Father has chosen. The term 'world' in this context is interpreted to mean all kinds of people from every tribe and nation, not that Christ's death was for every individual. This distinction is critical in Reformed theology, as it emphasizes God's sovereign grace in salvation.
