Why is the significance of bread and wine in Melchizedek's offering?

In Genesis 14:18, Melchizedek offers bread and wine to Abram, which is significant as these elements represent the future sacrifice of Christ. Unlike the animal sacrifices required under the Law, Melchizedek’s offering suggests the essence of Christ’s sacrifice that would eventually fulfill all sacrificial systems through His death and resurrection. The bread and wine served not only as a physical sustenance but also a spiritual foreshadowing of the body and blood of Christ, culminating in the institution of the Lord’s Supper. This highlights how Melchizedek’s offering was not merely an act of hospitality but a divine pointer to the ultimate redemptive work of Christ that was ordained from eternity.
