Who are the 70? Where did they come from?
Luke 10:25 And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life?
26 He said unto him, What is written in the law? how readest thou?
27 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
28 And he said unto him, Thou hast answered right: this do, and thou shalt live.
29 But he, willing to justify himself, said unto Jesus, And who is my neighbour?
30 And Jesus answering said, A certain man went down from Jerusalem to Jericho, and fell among thieves, which stripped him of his raiment, and wounded him, and departed, leaving him half dead.
31 And by chance there came down a certain priest that way: and when he saw him, he passed by on the other side.
32 And likewise a Levite, when he was at the place, came and looked on him, and passed by on the other side.
33 But a certain Samaritan, as he journeyed, came where he was: and when he saw him, he had compassion on him,
34 And went to him, and bound up his wounds, pouring in oil and wine, and set him on his own beast, and brought him to an inn, and took care of him.
35 And on the morrow when he departed, he took out two pence, and gave them to the host, and said unto him, Take care of him; and whatsoever thou spendest more, when I come again, I will repay thee.
36 Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves?
37 And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise.
Why does the Lord allow this man to fall among thieves? That is the same thing as asking why does the Lord send us out as lambs among wolves. To be stripped of your raimant is to be humiliated, robbed of your righteousness as a covering. Think about a woman being raped. Or a man who is convicted of a felony. These are permanent stains. Not only so but he was injured. Think of the injuries and losses we can go through in life that are also in many ways permanent. Think about being "half dead" when you got saved and turned to the Lord and nursed back to health. Experiences like that can become a "governing vision". You have empathy for all who are in the same condition and you know how to nurse them back to health since you were nursed back to health. You remain permanently changed on the outside, which is why you are now a "samaritan" but on the inside you are in the image and likeness of the Lord Jesus, which is why you go and do likewise. The Lord allowed this because you have to go through an experience like this before you will be motivated to go through everything required to be one of the seventy.
Suppose you went through something like this and then decided to become a Navy Seal. The training was brutal, but you didn't quit because you knew if you quit you would always be defeated for your whole life. Now, once you have completed that training you are not the one who is defeated by serpents and scorpions, rather you are the one treading on them. Satan is not the one tormenting you, rather you are the one making Satan fall from his spot in the sky like lightning.
Satan is not scared of the majority of Christians, but he is scared of the 70.
