When Jesus said "GO into ALL the World", He meant what He said. It is crucial, to train and equip believers for the harvest, because the great commission cannot be fulfilled just by preachers. Every believer is called to learn to live his life supernaturally natural and to demonstrate the love and power of God, that´s why this is a big piece of the mission of GKM. Jesus wants to touch people all the time, no matter if it is the person on the street or the tens of thousands in large gatherings. 

And as you go, preach, saying, ‘The kingdom of heaven is at hand.’
Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give.
- Matthew 10:7-8
