What does the Bible say about God's silence in prayer?

In Psalm 77, the psalmist expresses a deep yearning for God while feeling abandoned in prayer. Although he cried out to God earnestly and felt that his prayers were not being heard, the Scripture reassures us that God always hears His people, particularly for the sake of Christ, our intercessor (Isaiah 65:24). This apparent silence serves a purpose; often, it brings believers to the end of themselves, teaching them to await God’s timing and to trust His promises. In Lamentations 3, it's emphasized that God covers prayers not to dismiss them, but to deepen our reliance on Him alone.
