How do we know that Christ’s washing is essential for our salvation?

In John 13:8, Jesus told Peter, 'If I wash thee not, thou hast no part with me.' This powerful statement underscores the necessity of Christ's sacrificial act for our salvation. His washing signifies the cleansing from sin that is essential for being united with Him. This cleansing is not merely symbolic; it reflects the profound truth of the gospel, which reveals that salvation is found in Christ's atoning death and resurrection. Without His cleansing, believers cannot have a relationship with Him or partake in the benefits of His work.
