How do we know we need daily forgiveness as Christians?

In John 13:10, Jesus explains to Peter that while one who has been washed is clean, they still need their feet washed due to the daily defilement experienced in a sinful world. This metaphor emphasizes that even after initial salvation and justification through Christ's blood, believers must continually seek and receive forgiveness for ongoing sins. This necessity for daily washing aligns with 1 John 1:9, which assures us that if we confess our sins, He is faithful and just to forgive us. Regular communion with God in repentance highlights our ongoing need for His grace and the importance of remaining in fellowship with Him as we journey through life.
