As Psalm 18:46,47 tell us, in the midst of his battles, David could shout:

“The LORD lives! Praise be to my Rock! Exalted be God my Savior! He is the God who avenges me, who subdues nations under me,”

[As far as we know, David was never defeated in battle and never was seriously wounded--because God protected him. "The LORD is my rock...my deliverer... my shield" (Psalm 18:2). And David remembered this, giving God the credit.]

Psalm 18:48 “He is the God…who saves me from my enemies.”

[Yes, O Lord God, it is true that when “I call to you, who are worthy to be praised...I am saved from my enemies…You reach down from on high, you take hold of me, you draw me out of deep waters” (Ps. 18:3,16). You are the faithful One who constantly watches over me, not primarily for my comfort, but for my being able to give you glory before the nations.]

So in the midst of my own troubles,(the nasty neighbor has announced today he is suing me because he fell down the stairs, conveniently on the day he got his eviction notice!) I can place my trust in the Lord, for as David wrote In Psalm 34:15-17 “The eyes of the LORD are on the righteous, and his ears are attentive to their cry; but the face of the LORD is against those who do evil, to blot out their name from the earth. The righteous cry out, and the LORD hears them; he delivers them from all their troubles.”
