What does the Bible say about being clean before God?

In Exodus 30:17-21, the need for cleansing is vividly illustrated through the brazen laver, which the priests used to wash their hands and feet before approaching God. This symbolism reveals our natural state of sinfulness, showing that we are unclean by nature and in need of redemption. The brazen altar, representing Christ's sacrifice, must precede the laver, emphasizing that only through the blood of Jesus can we be made clean. This cleansing is further explained in Titus 3:5, where the washing of regeneration and the renewing of the Holy Spirit are linked to our salvation. Thus, to be clean before God, one must first come to the sacrifice of Christ, then experience the regeneration of the Holy Spirit to be clean in heart and conscience.
