How is God a rock? (Psalm 18:2; Psalm 18:31; Psalm 19:14)

How is God a rock? (Psalm 18:2; Psalm 18:31; Psalm 19:14) 

The Lord is my rock, my fortress and my deliverer;
    my God is my rock, in whom I take refuge,
    my shield and the horn of my salvation, my stronghold. (Psalm 18:2)

For who is God besides the Lord?
    And who is the Rock except our God? (Psalm 18:31)

May these words of my mouth and this meditation of my heart
    be pleasing in your sight,
    Lord, my Rock and my Redeemer. (Psalm 19:14, NIV)

IS GOD A ROCK IN THE SAME SENSE THAT KING DAVID REFERRED TO IN Psalms 61:2?
