‘When making decisions, requests for signs from God should be confirmatory, rather than predictive. Gideon twice laid a fleece before the Lord in order to confirm what God had said (Judges 6:36-40). It is important to note that the fleece was laid after the decision to go into battle to save Israel had actually been made – it was not a way of shirking responsibility. Requests for signs should, therefore, be confirmatory (although God may intervene) rather than predictive and need be made only in special cases.’ – Ken Costa
