his sermon explores the consecration and ordination of the Old Testament priesthood, focusing on the necessity of blood sacrifice as seen in Exodus 29 and Leviticus 8. Though the priests were washed, clothed, and ordained, they were not fit to serve until blood was shed—foreshadowing the atoning work of Christ. The sermon emphasizes that outward righteousness is insufficient without inward cleansing, and only through the substitutionary death of Jesus can anyone be made truly clean. It calls believers to examine their hearts, submit to God’s Word, and place their full trust in the finished work of Christ alone for salvation.
