What does the Bible say about quickening the spirit?

In Psalm 143, David expresses a deep longing for spiritual revival by asking God to 'quicken' him, which indicates a desire for life and renewal. This prayer for quickening is only possible for those who have been given life by God, as a spiritually dead person does not recognize their need for life. The request to be quickened is often rooted in the understanding that one's own efforts or righteousness are inadequate, and hence they appeal to God for revival based on His mercy and grace.
