In the biblical narrative, tears often symbolize deep emotional experiences, ranging from sorrow and repentance to longing and spiritual thirst. The concept of tears as sustenance is a poignant metaphor found in Scripture, illustrating the profound connection between human suffering and divine provision.

Psalm 42:3
The psalmist laments, "My tears have been my food day and night, while men say to me all day long, 'Where is your God?'" . Here, tears are depicted as a form of sustenance, consumed continuously in a time of distress. The psalmist's tears reflect a deep spiritual hunger and thirst for God, as he endures the taunts of those questioning God's presence. This verse captures the essence of tears as both a physical manifestation of grief and a spiritual cry for divine intervention and comfort.

Psalm 80:5
In another instance, the psalmist cries out, "You fed them with the bread of tears and made them drink their full measure of tears" . This imagery of tears as both bread and drink underscores the depth of Israel's suffering and the intensity of their need for God's deliverance. The tears serve as a reminder of the people's dependence on God, even in times of judgment and hardship.

Lamentations 3:48-49
The prophet Jeremiah expresses his sorrow for the destruction of Jerusalem, saying, "Streams of tears flow from my eyes because of the destruction of the daughter of my people. My eyes overflow unceasingly, without relief" . Jeremiah's tears are a testament to his profound grief and intercession for his people. In this context, tears become a form of spiritual sustenance, fueling his prayers and pleas for mercy.

Spiritual Significance
Tears as sustenance in the Bible often point to a deeper spiritual reality. They are not merely expressions of human emotion but are intimately connected to one's relationship with God. In times of trial, tears can become a means through which believers draw closer to God, seeking His presence and comfort. The act of weeping is transformed into a spiritual discipline, where the soul is nourished by the hope and promise of divine intervention.

New Testament Perspective
In the New Testament, Jesus Himself is described as one who wept (John 11:35). His tears at the tomb of Lazarus reveal His compassion and empathy for human suffering. Jesus' tears also foreshadow the ultimate sustenance He provides through His sacrifice, offering eternal life and comfort to those who believe in Him.

Revelation 7:17
The promise of God wiping away every tear from the eyes of His people (Revelation 7:17) signifies the ultimate fulfillment of divine sustenance. In the eschatological vision, tears are no longer needed as sustenance, for God Himself will provide for every need, eradicating sorrow and pain.

In summary, the biblical portrayal of tears as sustenance serves as a powerful reminder of the human condition and the hope found in God's provision. Through tears, believers are drawn into a deeper reliance on God, finding spiritual nourishment in His presence and promises.
