Why is it necessary for Christians to be cleansed regularly?

Christians need regular cleansing to ensure that their fellowship with God remains untainted. The brazen laver serves as a reminder that even though we are eternally secure in our salvation, our earthly walk can lead to spiritual dirt. This essentially means that our daily actions and thoughts can hinder our worship and communion if we are not continually cleansed. Scriptures like 1 John 1:9 assure us that confessing our sins allows us to be cleansed from all unrighteousness, thus emphasizing the recurring need to return to Christ for that purification.
