"For as many as are led by the Spirit of God, they are the sons of God" - God through Paul. Thus those who are not COMMANDED by GOD to do any work for his sake yet do it anyway are liars. Thus God said, "Cursed be he who doeth the work of the Lord deceitfully". Those who are ordained by God are also prepared by God and those men shall have fruit as proof to the command that God gave them to go. If God did not command you. Do not Go.
