Perhaps the most astonishing characteristic of Jesus’ praying is that when He prayed for others He never concluded by saying “if it be Thy will.” Nor did the apostles or prophets when they were praying for others. They obviously believed that they knew what the will of God was when they prayed the prayer of faith. They were so immersed in the milieu of the Holy Spirit that when they encountered a specific situation, they knew what should be done. Their praying was so positive that it often took the form of a direct, authoritative command: 

“Walk”

“Be Well”

“Stand up!”

I saw that praying that when praying for others there was evidently no room for indecisive, tentative, half-hoping, “if they it be Thy will” prayers.
