How do we know that belief in Jesus saves us?

We know belief in Jesus saves us through the promises found in Scripture, specifically in 1 Peter 2:6 which declares, 'He that believeth on him shall not be confounded.' This assurance is rooted in God's covenant and the work of Christ, who fulfilled the law and atoned for our sins. The certainty of our salvation is not based on our merit but rather on Christ's sacrificial death and resurrection which guarantees our acceptance before God. Thus, belief in Him is foundational for our reconciliation and assurance.
