What to do?

Yours truly has been extended a call. Now the question is, "what is the will of God for us?" It has always seem to me this is one of the toughest questions to ask. It is not like I can go to scripture and read, "Dr. Luther, you shalt taketh the call that cometh during the sixth month of the 232nd year of the land beyond the sea." So now I have to rely on those tainted sources of reason and feelings. Is that God telling me to take the call or is it heartburn. So, in my moment of indecision please pray for us as we consider this wonderful new opportunity to serve the Lord.
