As the disciples would cooperate with Heaven in the promulgation of the gospel, they could rest assured that the boundless resources of Omnipotence were at their disposal. God would supply their every need and honor the petitions lodged before the throne in the name of Jesus.

The fact that men are to petition the Father in the name of Jesus, but that Jesus is the one who brings about the answer, emphasizes the oneness of the Son with the Father. In chs. 15:16; 16:23 the Father is said to answer the petitions presented before Him.
