Taking something out of context and then trying to apply it to something that God never said to do is unscriptural.
Like I said before using your approach would mean that all Christians should walk around naked for three years like Isaiah did.
Or we could simply make every decision infallibly, including decision whether we are right on understanding passages of scripture simply by drawing lots.
Or as Homesell suggested, we could give God two options that we want and ask Him to tell us which is His choice.
Taking something out of context does not mean that it has God's endorsement.
