How do we know that Christ's death saves us?

The assurance of salvation through Christ's death is rooted in the theological understanding of propitiation and redemption. In the scriptures, particularly in Galatians 6:14, we learn that Christ’s death was not simply a token of love; it fully satisfied God's justice on behalf of His people. Christ bore the sin debt of those He came to save, making a sacrificial payment that secured their eternal salvation. Those for whom Christ died can be confident they will never perish, as His atoning work achieved complete redemption. This foundation leads to the understanding that salvation is not contingent upon human effort but is entirely the work of Christ, reinforcing the belief that He died for the elect.
