Psalm 18 is a long psalm. 18:30-34 is a strong word, a word about God that leads us to learn to trust in God and to depend on God, especially when life seems to be at its worst. Here the psalmist speaks of what God is like:
18:30 The one true God acts in a faithful manner;
the Lord‘s promise is reliable;
he is a shield to all who take shelter in him.
18:31 Indeed, who is God besides the Lord?
Who is a protector besides our God?
18:32 The one true God gives me strength;
he removes the obstacles in my way.
18:33 He gives me the agility of a deer;
he enables me to negotiate the rugged terrain.
18:34 He trains my hands for battle;
my arms can bend even the strongest bow.
