They need not depart signifies that all spiritual sustenance is found in Christ, thus there's no need to seek fulfillment elsewhere.
The phrase 'they need not depart' encapsulates the core message of dependency on Christ for all spiritual needs. In the sermon, it is emphasized that the multitude did not need to leave His presence in search of food because Christ Himself is the ultimate fulfillment of all human needs, both physical and spiritual. When Christ instructs the disciples to give the people something to eat, it highlights the responsibility of believers to share the life-giving words of Christ with those around them. This statement reinforces the truth that every believer has access to everything they need for life and godliness through Christ. Thus, it serves as both a comfort and a commission to rely solely on our Savior.
