That picture reminded me of the biblical discription of the Lord as being "the Rock of Israel." I believe the picture expresses a lot of what the following passage has to say:

"22Joseph is a fruitful bough, a fruitful bough by a spring; his branches run over the wall. 23 The archers fiercely attacked him; they shot at him and pressed him hard. 24 Yet his bow remained taut, and his arms were made agile by the hands of the Mighty One of Jacob, by the name of the Shepherd, the Rock of Israel, 25 by the God of your father, who will help you, by the Almighty who will bless you with blessings of heaven above, blessings of the deep that lies beneath, blessings of the breasts and of the womb. 26 The blessings of your father are stronger than the blessings of the eternal mountains, the bounties of the everlasting hills; may they be on the head of Joseph, on the brow of him who was set apart from his brothers." Gen 49:22-26

Wow, what a blessing!
