This is exactly what Christ asked the 12 to do. He asked them to leave everything, take nothing, follow Him, and then go share what they had learned in His presence. That is scary stuff. The only way that makes any kind of sense is there is a sovereign God who has called me to do that. If He is not in control, if He is not about bringing people into His kingdom through sending me to get them with no thought of self protection; I am insane to engage. On the other hand if God is sovereign and I can trust in His control of the situations and culture, I can boldly engage knowing that my “living sacrifice” serves His purpose. This seems to me yet another reflection of Hebrews 11:6, we have to believe that He is, and that He is a rewarder, a protector, of those who seek Him.
