Praying in the name of Jesus is extremely powerful. Through prayer, we can literally change the course of human history.
Unfortunately, most people do not understand what it means to pray “in Jesus' name.” Most people just say a prayer and then simply tack on the words “in Jesus' name” at the end of the prayer, but this is done out of ritual, and becomes a form of legalism.
In this episode, Kenny explains that praying “in the name of Jesus” means to pray in the manner Jesus would pray and to pray for things that Jesus would pray for. If you are asking God for the things that Jesus Himself would have asked for, when He was on planet Earth, and you pray with the same attitudes and sentiments with which Jesus would have prayed, then you are praying “in his name” even if you don't actually say those words at the end of the prayer.
