Naomi now takes the initiative in finding a husband for Ruth. Now this goes right against our culture, but it was normal in those days, and given the state of relationships in Western society we should be a little wary of claiming that our way is better (I hasten to add that I neither am I promoting arranged marriages! Just saying we have limited grounds for feeling superior!).
Naomi tells Ruth to prepare herself and go and sleep at the feet of Boaz. She was in effect saying that she wanted to marry Boaz. Again we find these actions strange, and possible strange that such things could happen without any sexual activity occurring. This again is a comment on the state of our society.
Boaz, as always, acts honourably. He is touched by Ruth's actions, but knows that there is another family member who has prior claim. So he will consult with this other relative before taking further action.
So we see patience being put into action as well. Even if we are convinced that something is God's plan, we should still follow proper procedures and not cut corners. If it is indeed God's will, then things will work out.
