How do we know prayer in Jesus' name is effective?
Answered in 2 sources
The effectiveness of prayer in Jesus' name is assured by Christ Himself, who promises that if we ask in His name, we will receive.
In John 16, Jesus instructs His disciples to ask the Father in His name, emphasizing that this new way of praying is foundational for their relationship with God. Until this moment, they had not fully realized His role as the Mediator between God and man. This teaching underlines a crucial aspect of Christian faith: that believers can approach God directly through Christ. Jesus encourages His followers to persist in prayer, assuring them that their petitions will be heard, which speaks to the intimate access they have to the Father through Him.
