What does the Bible say about prayer and God's response?

In Psalm 143, David demonstrates the attitude of coming before the Lord with heartfelt supplication, reminding us that prayer should be an acknowledgment of our dependence on God’s grace. He implores God to hear his prayer, recognizing that without divine intervention, he is powerless. The scripture illustrates that God does not owe us an audience; it is only by His faithfulness and righteousness that we have hope in prayer. In times of distress, true prayer reflects our deep need and recognition of our sins, asking for your mercy based on Christ’s redemptive work rather than on our merit.
