There are a number of reasons why individuals should consider engaging in prayer, even if they believe God already knows what is in their hearts and minds. First and foremost, prayer is an expression of love. Individuals can say they love God and his teachings, but this love must be communicated in some way.
Prayer is also an expression of gratitude. As is referenced multiple times throughout the Bible, all good things are a gift from God, and every gift warrants a proper thanks. Praying is the most direct and effective way to express one’s gratitude for the many gifts God provides. Finally, praying is an ideal way to spread the message of God and share His glory with others. Prayer is itself a gift from God, and when a prayer is answered, the natural response is to celebrate and share the good fortune through further prayer.
