According to the teachings, will any of those for whom Christ died be lost?

The assertion that Christ's death is effective for the elect is rooted in the doctrine of limited atonement, which is a significant theological concept within certain Christian traditions. This belief holds that Christ's sacrificial death was specifically intended to save those whom God has chosen, often referred to as "the elect."

According to this teaching, the effectiveness of Christ’s atoning work guarantees that all for whom He died will ultimately be saved. This view emphasizes the sovereign nature of God’s grace and the assurance of salvation for believers, indicating that none of the elect can be lost. This is central to many Reformed theological perspectives, which assert that the reconciliation provided by Christ's death cannot fail to produce salvation for those it was intended to save.

In contrast, the other choices suggest conditions or limitations that undermine this assurance, whereas the correct answer confirms the effectiveness of Christ’s atoning sacrifice for the elect, affirming the certainty of their salvation.
