What assurance do we have that God hears our prayers? In Psalm 5, David asks God to hear his groaning and cries. The king was confident that God listens to the repentant, humble heart, which relies upon God's steadfast love. David was not disappointed.
Since confidence is defined as a sense of self-assurance, we may assume that the source of confidence can be found within us. We simply need to boost our own morale. That is not the teaching of Scripture. In this series from the Psalms, Dr. John points to God as the foundation and sustenance for our hope in this life and the life to come.
