Why is feeding on Christ important for spiritual life?

In John 6:53, Jesus underscores the importance of spiritual sustenance by stating, 'Except ye eat the flesh of the Son of Man and drink His blood, ye have no life in you.' This metaphorical expression illustrates that true life—eternal life—is found in a close, personal communion with Christ. Just as our physical bodies require nourishment to sustain life, our spiritual lives necessitate feeding upon the truth of Christ and His sacrifice. This feeding is not about physical consumption but about internalizing the work of Christ, engaging deeply with the Scriptures, and having our hearts transformed by the truths of the gospel. A consistent focus on Christ as our spiritual sustenance strengthens our faith and equips us to bear fruit for Him.
