The thanksgiving offering, often referred to as a peace offering, fellowship offering, praise offering, or vow offering, was an animal sacrifice in ancient Israel that embodied praise toward God. This offering, as detailed in Leviticus 3:1-5, had to be without blemish and was to be offered freely, of one's own will, to be acceptable to the Lord. The sacrifice involved specific parts of the animal being burned on the altar as an offering made by fire, described as a sweet aroma to the Lord, indicating no sin was involved in the giving and thus satisfying to Him. The thanksgiving offering was layered on top of the burnt offering and meal offering, symbolizing a hierarchy of devotion and reverence. This offering was entirely voluntary, viewed as a privilege rather than a duty, and held a celebrative role, emblematic of joy and celebration, particularly on feast days. God desires that such offerings, including those given on holy days, be presented freely and with pure motives, reflecting an inner attitude of thankfulness. The sacrificial laws of the Old Covenant focused on outward conformity but could not dictate inner attitudes, yet the thanksgiving offering required a genuine, unblemished spirit in its giving. Applying this spirit to modern offerings, giving thanks for God's grace becomes a refined expression of seeking more of His favor, offered with anticipated thanks and faith in His promises. For offerings to be acceptable today, they must be given freely, without blemish, and as a sweet aroma to the Lord. They should not come from ill-gotten gains or be offered by those flagrantly sinning without remorse. Instead, offerings must be accumulated through personal effort, given faithfully and thankfully, mirroring the heart of the ancient thanksgiving offering.

The concept of the "Offering, Sweet Smelling" is central to understanding the burnt offering as a representation of complete devotion to God. The burnt offering is described as a sweet savor to God, indicating that it is pleasing to Him. This stands in contrast to the sin and trespass offerings, which are not sweet to Him and are burned far from His presence, outside the city gates. The burnt offering, however, is offered on the brazen altar outside the Temple and Tabernacle, with its fragrance wafting into the place of God's presence, satisfying Him as He receives the sweet aroma of the cooking meat. This pleasing nature reflects God's desire for us to be a living sacrifice, mirroring the life of Jesus Christ, who Himself was a sweet smelling savor to God through the way He conducted His life. The emphasis is on life, not death, highlighting God's concern for how we live in devotion to Him.
