Passage
Restore to me the joy of Thy salvation, And a willing spirit doth sustain me.
Restore to me the joy of Thy salvation, And a willing spirit doth sustain me.
Psalms 51:10 A clean heart prepare for me, O God, And a right spirit renew within me.
Psalms 51:11 Cast me not forth from Thy presence, And Thy Holy Spirit take not from me.
Psalms 51:12 Restore to me the joy of Thy salvation, And a willing spirit doth sustain me.
Psalms 51:13 I teach transgressors Thy ways, And sinners unto Thee do return.
Psalms 51:14 Deliver me from blood, O God, God of my salvation, My tongue singeth of Thy righteousness.
The verse centers on "Spirit", "restore", "salvation", "willing", "doth", and "sustain". It is saying that the verse draws attention to "Spirit" and "restore", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "Cast me not forth from Thy presence..." into verse 13's "I teach transgressors Thy ways And sinners...", so "Spirit" and "restore" 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 "Spirit" and "restore" with trust shaped by these words, not by a vague optimism outside the passage.
