What does the Bible say about spiritual food?

In Scripture, physical terms like 'meat' and 'bread' often symbolize spiritual sustenance necessary for spiritual life. In John 4:31-38, Jesus explains to His disciples that His true sustenance comes from doing the will of the Father. This concept illustrates that while we consume physical food to maintain our physical bodies, spiritual food—symbolized by Christ as the bread of life—is what nourishes our souls. Just as the Israelites were fed with manna in the wilderness, believers are spiritually fed through Christ and His work.
