Passage
The God who girdeth me with strength, and maketh my way perfect,
The God who girdeth me with strength, and maketh my way perfect,
Psalms 18:30 As for God, his way is perfect; the word of Jehovah is tried: he is a shield to all that trust in him.
Psalms 18:31 For who is God save Jehovah? and who is a rock if not our God?
Psalms 18:32 The God who girdeth me with strength, and maketh my way perfect,
Psalms 18:33 Who maketh my feet like hinds' [feet], and setteth me upon my high places;
Psalms 18:34 Who teacheth my hands to war, and mine arms bend a bow of brass;
The verse centers on "girdeth", "strength", "maketh", and "perfect". It is saying that the verse draws attention to "girdeth" and "strength", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 31's "For who is God save Jehovah and..." into verse 33's "Who maketh my feet like hinds' feet...", so "girdeth" and "strength" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "girdeth" and "strength" with trust shaped by these words, not by a vague optimism outside the passage.
