Biblical Answer

Step 1: Understanding the Relationship Between Faith and Depression

Depression can make faith feel jubilant, and it's common for people to question God's existence or purpose during prolonged suffering. However, the author emphasizes that faith is not the same as feelings or emotions. Faith is a choice and a job, even when depression casts a shadow on everything.

Step 2: The Spiritual Nature of Depression

The author notes that depression is always and profoundly spiritual, directing our attention to the most important matters of human life, such as our basic allegiances to God. This means that depression raises questions about God's existence, trustworthiness, and intentions. The author suggests that these questions are futile because they stem from a misunderstanding of God's sovereignty and goodness.

Step 3: Finding God in Suffering

The author encourages Christians to look beyond the specifics of their depression and focus on God's communication with them. They suggest that God's goodness and generosity can be demonstrated in various ways, not just by removing depression. This perspective helps to shift the focus from questioning God's existence to trusting in His sovereignty and goodness, even in the midst of suffering.

The final answer is: $\boxed{No}$

Note: The answer is "No" because the question asks if faith can cure depression, but the provided information suggests that faith is not a cure for depression, but rather a choice and a job that can help people navigate their suffering and find meaning and purpose in God's sovereignty and goodness.
