There are several implications in this account of Jesus' walking on the sea following the Feeding of the Five Thousand. It describes Jesus' self-manifestation to the disciples - revealing His divine power over the forces of nature - control over the sea (Is. 43:16).
The words 'I am' are not only words of comfort to the fearful disciples but with a deeper meaning like that in the Old Testament (Ex. 3:14). The fear of the disciples implies their lack of faith and understanding and the epiphanic or revelatory nature of the event. On the other hand, it may refer to the reaction of the disciples as one who is in the presence of the divine. (Ps 71 ¡K 'all the nations shall fall prostrate before you, Lord.') If confirms the failure on the part of the disciples to recognize the true nature of Jesus.
This passage helps us to reflect on our experiences of the 'wind' blowing against us in our lives. Were we able to recognize God's presence and power in such situations? Under such circumstances do we believe in the love God has for us in the first reading, "In love there can be no fear but fear is driven out by perfect love"?
Lord, help us to trust You completely in whatever may happen to us on earth.
