Why is daily cleansing important for Christians?

The need for daily cleansing as a believer is highlighted in the sermon through the typology of the brass laver. While justification is a final and complete work, the ongoing process of sanctification requires believers to seek cleansing from daily defilements caused by sin. This concept is reinforced in 1 John 1:9, which states that if we confess our sins, He is faithful and just to forgive us and to cleanse us from all unrighteousness. Here, the continuous need for purification illustrates that, though we are justified, we still carry a sinful nature that must be addressed to maintain our relationship with God and to prepare ourselves for worship, emphasizing the necessity of repentance and reliance on the Holy Spirit's work within us.
