How do we know God's mercy is sufficient when we face trials?

In Psalm 13, David transitions from questioning God's presence to declaring his trust in His mercy, stating, 'But I have trusted in thy mercy.' This reflects the assurance that God’s mercy is sufficient regardless of our circumstances. Throughout scripture, we see that our trials are not without purpose; they drive us to rely more deeply on God's grace. His mercy through Christ assures us that even in suffering, we can find hope and reason to rejoice as we anticipate His deliverance and comfort. David's declaration of rejoicing in God’s salvation confirms that we should anchor our trust in His character and not solely in our circumstances.
