The cereal offering represents a blameless life. The purity of its ingredients is emphasized (see 2:1, 11).
The worshipper who is not blameless draws near to God with acceptance in the power of an offering possessing the perfection that he lacks. Consider how this offering is fulfilled in Christ. Cf. Heb. 7:26; 1 John 2:6.
The peace offering speaks of communion, based on the blood of atonement (3:1, 2), and expressed in a whole burnt offering pleasing to the Lord (3:5).
Do you know the heart-satisfaction of such a relation to God?
