Rick Renner suggests that "by praying in Jesus' name, a believer actually stands in the physical place of Jesus who is in Heaven, acting on His behalf and operating in the authority He has vested to that believer as His official representative."
Thus, this prayer of the elders in James 5 is prayed by someone who understands he is standing by the bedside of the sick on Jesus' behalf. As the representative of Jesus Christ, this elder has the right to call on the power of God and to exercise all the authority that belongs to Jesus.
What would Jesus do if He were physically present in the situation? That is precisely what this leader is to do as he ministers to the sick in the very stead of the Master."
