How do we know Christ's death was for sinners?

The belief that Christ died for sinners is grounded in the biblical recognition of His purpose in coming to earth. Luke 19:10 explicitly states that Jesus came to seek and save the lost, meaning His sacrificial death was intended for those who are aware of their sinfulness and inability to save themselves. Importantly, this assurance isn't based on a person's inherent worthiness but on faith in Christ's finished work. The gospel underscores that those who recognize their need for a Savior and call upon His name will find reconciliation with God, affirming the specific nature of His atonement.
