In defense of numbers and the word of God,
The disciples were following strict orders from Jesus who was following strict orders from God.
The gospel had to FIRST be preached to the Jews
Matthew 10:5-10 These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel. And as ye go, preach, saying, The kingdom of heaven is at hand. Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give. Provide neither gold, nor silver, nor brass in your purses, Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.
When Jesus knew his death was at hand he prepared his disciples to preach to Gentiles as well.
Luke 22:35-36 And he said unto them, When I sent you without purse, and scrip, and shoes, lacked ye any thing? And they said, Nothing. Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
After his death and ressurection they were given NEW orders.
Mark 16:14-16 Afterward he appeared unto the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen. And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
