This sermon examined Exodus 30:1–10 and the significance of the golden altar of incense. It highlighted the altar's construction, purpose, and placement in the tabernacle as typological of Christ's mediation. Drawing from the example of Nadab and Abihu, it warned against worship that is unauthorized and self-willed. The message emphasized that true worship must be continual, grounded in the finished work of Christ, and conducted according to God's Word. It concluded with a call for self-examination and a renewed commitment to worship the Lord in spirit and in truth, offering only what He has commanded and accepting no substitutes.
