How should a Christian put a decision in God's hands if there is no logical answer?

Lets say a Christian is in a position where he must make a hard decision (assume it has to either be a yes or no by a deadline) and each one has negatives consequences (more negatives than positives). How should a Christian pick one option over another? Both options can and will affect the future of himself and others, but it is impossible to tell which one will impact the least or which one is a better decision, only time will tell. Based on Christian teaching, if Jesus specifically was talking to that person, how would he advise, or what are some things he would tell the person to keep in mind? I am sorry it is not specific but I can't put details to it. So if it helps, the main part of the question is how should a Christian put a decision in God's hands if he really doesn't see a logical answer but has to pick one? (I am also assuming the person was put into making that decision by God?... since he would rather not be in such a situation...)
