What does the Bible say about the effect of prayer?

The assurance that God hears prayer is a profound comfort to believers, as depicted in Psalm 65:2, which states, 'O thou that hearest prayer, unto thee shall all flesh come.' This promise emphasizes God's attentiveness to the prayers of His covenant people. It encourages Christians to approach the throne of grace with confidence, knowing that their cries are not in vain. Furthermore, this understanding fosters a relationship of intimacy with God, as believers acknowledge their dependence on Him. In Christ, prayers are made with the confidence that He intercedes on behalf of His people, assuring them that they will receive mercy and grace in their time of need.
