Seasoned With Salt

Lev 2:13 You shall season all your grain offerings with salt. You shall not let the salt of the covenant with your God be missing from your grain offering; with all your offerings you shall offer salt.

Could Jesus be alluding to this passage when he says, "You are the salt of the earth?" I don't think that was his primary meaning in the Sermon on the Mount, but it's an interesting aspect of being salt. What can we learn from this passage in Leviticus about our role as salt? We are to offer ourselves with all our offerings of firstfruits. A heartless offering, no matter how large, if it doesn't have a piece of myself, is an improper offering. This is the point of Jesus' teaching about the woman who offered two small pennies--it was all she had; she gave of herself.
