The fine flour here typifies the humanity of Jesus. This indicates that we commit sins not only because we have sin in our nature and not only because we are not absolute for God (see note Lev. 5:71) but also because we do not have the humanity of Jesus. In His humanity Jesus has no sin in Him and is absolutely for God. The tenth part of an ephah of fine flour offered for a sin offering signifies that only a small portion of the humanity of Jesus is needed to kill the negative things within us and to supply our need.
