Powerful prayer works! The original Greek of the Bible often uses a special word for power: dunamis – it signifies miraculous, wonder-working power. From it we get the words dynamo (which generates power), and dynamite (the explosive). If you want prayer to work, to change your circumstances, then it must generate power. Jesus never once in the four Gospels told His disciples to pray for the sick. He said, ‘HEAL the sick!’ (Luke 9&10). He was speaking with authority! Yes, in James 5:14 it says ‘the prayer of faith will save the sick’ – but this is in the church. There is a big difference between the call of the evangelist and ministry within the church.
