Why does David describe himself as poor and needy?

In Psalm 12, David's reference to being 'poor and needy' illustrates the spiritual condition of all true believers—recognizing their inability to save themselves and their complete reliance on God's mercy. This humility allows for an acknowledgment of sinfulness and the necessity of grace. As Christians, understanding this state encourages us to seek God earnestly for salvation, recognizing that we contribute nothing to our justification. It reinforces the concept of total depravity, reminding us that we must look outside ourselves for hope, which is found solely in Christ.
