Matthew 10:7 And as you go, preach, saying, ‘The kingdom of heaven is at hand.’
8 Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give.
Their mission: proclaim Christ is here. Be looking for opportunity to free people of their bondage. Stop turning away from such people. Invite them into the kingdom. And as you did and paid nothing, you will charge nothing. God is doing the work, you are a willing vessel.
This mission had to be very challenging for them. There is no comfort zone except in Jesus. They would have to trust in Jesus.
