Jesus said to the crowds, “I am the bread of life; whoever comes to me will never hunger, and whoever believes in me will never thirst.” (Jn. 6:35)
Jesus, our Savior and our God, is depicted by John as the Word who “became flesh and made his dwelling among us.” He proclaims Christ’s glory as “the glory as of the Father’s only Son, full of grace and truth.” (Jn 1:14) God, who “after speaking in many and varied ways through the prophets” , "now at last in these days has spoken to us in His Son" (Heb. 1:1-2).
A beautiful example of God speaking through his prophets and then through Christ comes directly from the mouth of David while in the wilderness of Judah. David cries, “O God, you are my God— it is you I seek! For you my body yearns; for you my soul thirsts, in a land parched, lifeless, and without water. My soul shall be sated as with choice food, with joyous lips my mouth shall praise you!” (Ps. 63:2&6) Then Jesus, the descendent of David and savior of Israel, answers David’s cry by offering his body as true food and true drink. No longer do we have to pine in the parched desert of life. With joyous lips we are able to come to the table and receive the choice food.
Let all the earth cry out to God with joy! Alleluia!
