Bob DeWaay on the wisdom approach to decision making:
God will not judge us for failing to “obey” PWsFG that we cannot know to be from Him. What God does tell us to do is ask for wisdom: “But if any of you lacks wisdom, let him ask of God, who gives to all men generously and without reproach, and it will be given to him” (James 1:5). Contrary to what some think, as we will see when we examine a passage later in James, this is not a prayer for a PWFG. It is a prayer that God would so work in our lives that we will make wise and godly decisions. This is much like the previous verses in James which teach that trials and testing produce endurance. God gives wisdom for decision making, but we make the decisions. The PWFG approach assumes that God wants to make every decision for us and that we need special revelation of God’s decision. But that produces “reproach,” which James says asking for wisdom does not. Why? Because if one thinks he has a PWFG and follows it, and the result is disaster, he comes under the reproach of assuming he heard wrongly. But when we ask for wisdom which is the result of the fear of God, love for the truth, our developing a Christian worldview and consequently developing Christian values, we make wise decisions.10 There is no reproach because we, within our Christian liberty and in light of our Christian values, made a decision. The outcome of our decision is unknown until God’s providential will is revealed as history unfolds. But there is no reproach because of the way we made the decision.
