How do we know that prayer in Jesus' name is powerful?

In John 14:13-14, Jesus makes a profound promise concerning prayer, stating that anything asked in His name will be granted. This assurance emphasizes the importance of praying in alignment with Christ's will and recognizing the power of His intercession. The expectation is not merely about acquiring earthly goods but receiving that which is genuinely good for our souls. The effectiveness of our prayers is deeply rooted in our relationship with Christ; when we approach God with earnest hearts and sincere aims, we are assured that our petitions will succeed as they are laid before a righteous and loving Advocate.
