To you Vanaze, I would say this to your friend:
Judges 6 : 36 - 40 "Gideon said to God, "If you will save Israel by my hand as you have promised- look, I will place a wool fleece on the threshing floor. If there is dew only on the fleece and all the ground is dry, then I will know that you will save Israel by my hand, as you said." And that is what happened. Gideon rose early the next day; he squeezed the fleece and wrung out the dew-a bowlful of water.
Then Gideon said to God, "Do not be angry with me. Let me make just one more request. Allow me one more test with the fleece. This time make the fleece dry and the ground covered with dew." That night God did so. Only the fleece was dry; all the ground was covered with dew."
If it is truly God's will, then ask God to help him see it clearly. For there are many demons who seek to act like angels of light, and this person needs to pray to God earnestly for definate spiritual nudging before embarking on such a mission.
As for those of you who replied to him, I say this to you:
Acts 5 : 35 - 39 "Then he addressed them: "Men of Israel, consider carefully what you intend to do to these men. Some time ago Theudas appeared, claiming to be somebody, and about four hundred men rallied to him. He was killed, all his followers were dispersed, and it all came to nothing. After him, Judas the Galilean appeared in the days of the census and led a band of people in revolt. He too was killed, and all his followers were scattered. Therefore, in the present case I advise you: Leave these men alone! Let them go! For if their purpose or activity is of human origin, it will fail. But if it is from God, you will not be able to stop these men; you will only find yourselves fighting against God."
I know you care for this individual and that you think it best if he does stay home and take care of things at home. But God does make plans, and he does use people in the most extraordinary of ways, even if we don't know about it or understand. So be very careful of the advice you give someone, telling them yes God said this or no, its a false God. You never know when you'll be fighting for good, or fighting against God.
