All our sins require purification, even unintentional ones (Lev 4-5)

We live in a culture that downplays sin, but these chapters remind us of the need for purification & cleansing. Even seemingly small or trivial omissions are a stench to God & keep Him from dwelling amongst a sinful people. We thank God that Jesus came to shed His blood, to wash our sins away, so that God can dwell with us.
