The Grain Offering was made without yeast and with salt. Any bread offered would be made with oil and frankincense. Yeast is often associated with things that are not godly. Jesus told the disciples to “beware the yeast of the Pharisees,” among other admonitions. When we bring a gift or bring ourselves as an offering before God, that gift should not be mingled with the things of the world. Rather, we should bring a gift that is anointed with the oil of the Spirit, and perfumed by the presence of God. It is then that our worship and offering to God will be acceptable and genuine.
The Peace Offering, especially if a member of the herd, had to be without blemish, and the offerer must identify himself with the offering by laying his hand on the animal’s head. Again, when we offer God an offering of any kind, we should give God our best, the absolute expression of the best we have to offer. We must also invest ourselves into the offering, giving God an offering that costs us something, much like David at the threshing floor of Araunah.
In the end, it is essential for Christian worshippers to offer God an unadulterated offering, with anointing and presence, that is the best we can give our Savior. God is looking for worshippers who give Him their best.
