If there's a decision you are having trouble making right now, what can you do that you have not done in the past to know what God's will is? It might be something like sitting quietly on the edge of your bed every morning before you begin your day and asking God for explicit guidance. Whatever it is, be sure it's something different from what you've done in the past.
Carefully listen and observe throughout the day for God's will. Sounds like an easy activity, doesn't it? Yet it's too easy to walk through life like a robot, endlessly repeating our daily tasks, oblivious to any direction other than yesterday's routine. If this is happening to you, obviously you'll want to change it. How? Observe, observe, observe!
Important: God doesn't speak in a loud voice. With open eyes, so you can see, open ears so you can hear, and an open heart so you can feel, you will have your answer. Richard and Mary-Alice Jafolla/Adventures on the Quest.
