Psalm 123

"To you I lift up my eyes,
O you who are enthroned in the heavens!
As the eyes of servants
look to the hand of their master,
as the eyes of a maid
to the hand of her mistress,
so our eyes look to the Lord our God
until he has mercy upon us."
Psalm 123:1-2

I wonder how many times I have heard someone say, "I wish I knew what God wanted me to do ..." (I've actually probably said it a time or two myself) It strikes me from this psalm that there is a very easy way to tell what it is that God desires and that is to simply look. When you have the opportunity to be waited upon by a really good waiter/waitress in a restaurant they seem to anticipate what you are going to want/need next and have it to you before you are even aware yourself of the want/need. The way they do this is by becoming a student of those they serve. They watch for the signs and become accustomed to the patterns of those they serve.
The key to anticipating God's desires though is to know where you are supposed to be looking. If you look only at that which is right in front of you it is easy to miss the source of God's guidance. So we have to look up and become accustomed to the ways God is at work. We can do this by reading the Bible, talking to others about their experiences with God, and reflecting upon our own life experiences. Over time if we are paying attention it should become second nature for us to know God's will because we are actively looking for it each and every day.
