I think we should rely on the Word of God. Today the greatest means of God's guidance is his Word, the Bible. Unlike Gideon w have God's complete, revealed Word. If we want to have more of God's guidance, don't ask for signs, pray and study the Bible. (2Tim 3:16-17). Demanding a sign may cause one to get in trouble with God. (Exodus 17:2, 7; Deut. 6:16).
