How do we know that prayer is powerful?

Paul highlights the importance of prayer in Philippians 1:19, where he credits the prayers of the saints as a means of his deliverance. James 5:16 affirms this by stating, 'the effectual fervent prayer of a righteous man availeth much.' This signifies that prayer is not a mere formality; rather, it is a powerful tool that God uses to enact His will and provide for His people. Our prayers engage us in the divine mission, asserting that God hears and responds to the earnest pleas of His children, thus illustrating the necessity of faithful prayer in the life of believers.
