“The effectual fervent prayer of a righteous man avails much”! ‘Effectual fervent’ means this is very powerful prayer. The Greek word used for powerful is ‘dunamis’. We use this word in English for a dynamo (to generate electricity, to generate power, to run your home, your car); and for dynamite (a very unusual explosive which doesn’t waste its energy on the open air, but pushes the wall down, breaks open the rock face). So when we’re talking about prayer, your prayer must not be wasted on the air, but like dynamite, it must be dynamic enough to move the mountain out of the way!
