How do we know God is faithful to answer our prayers?

David states in Psalm 143 that he seeks God's attention and asks for answers based on God's faithfulness and righteousness. This highlights the assurance that every sincere prayer is answered by God, though in His own time and manner. The notion of God as a faithful covenant keeper means that He will always fulfill His promises. We can trust in His willingness to respond to our prayers, especially when we approach Him acknowledging we have no righteousness of our own but rely on Christ for our standing before Him.
