The Lord is my rock, my fortress and my deliverer

2 Samuel 22:1-7
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.
He is my stronghold, my refuge, and my savior— from violent people you save me.
I called to the Lord, who is worthy of praise, and have been saved from my enemies.
In my distress I called to the Lord; I called out to my God. From his temple he heard my voice; my cry came to his ears.
This is virtually identical with Psalm 18, and can be compared with Moses's song in Deuteronomy 32. It belongs to the period of David's great early victories.
Why?
David wrote a song for the Lord, for he experienced the great salvation from the Lord.
In his distress, he called to the Lord, and the Lord saved him from death.
Be holy and conscious before the Lord, then our prayer could reach to the Lord and God will help us.
Rock, fortress and deliver means the stronghold to defense enemy or risk.
So I do not complain to any other for God is my salvation.

v1-4: 宣告
自然界的景物觸動他領受 大能。
岩石、磐石來形容神不改變，神的可靠，無論環境如何改變，神都不改變。
山寨、保壘：四周無處可躲的地方，得不到奧援的地方，神都在那裏支援我們。
拯救的角、高臺： 表示權柄高大，勝過一切。
所有細微的事、動物都在神的手中。
即使仍在仇敵手中，仍然讚美神，在危難中向主祈求必得著力量。
v5-7 描寫危險的情形。求告及呼求七次，這是我們唯一能做的。
讚美使我們得到力量。
V5-10 是摘要，急流： 急速來到，讓人措手不及。
從殿中聽我的聲音：在會幕表達神同在的真實性。與人生活在一起。聽到、聽見，而且神聽進去，有反應、有作為。

Honest pray to the Lord with all my heart, my mind, and my strength.
