Most of us have put such an emphasis on being in the center of the divine will of God that we lose the peace and rest that comes from letting Him guide us as He chooses. His purpose, His goal is not that we make the “right” choice or decision, but that we depend on Him to reveal what that decision is. As we mature in rest we will more and more find ourselves making decisions and choices without realizing it; not until after we find ourselves traveling in a new direction will we even notice, for our eyes and ears will be upon Him, not on our surroundings.
One of the benefits of gaining the confidence of knowing that we are hearing the Lord’s voice is we will become less dependent on the need for confirmation. As we begin, the Lord knows we need this encouragement, and will use confirmation, giving a sign in some way, for instance, that what we’ve heard or understood is from Him. Part of the process of learning to hear is not only testing what we hear, but also how it is confirmed; the devil is perfectly capable of confirming his word using the same means God does. So it’s important that we grow out of needing to have a confirmation. Once God knows He has our confidence, He will likely enjoy celebrating with us through confirmation, after we have stepped out or made a decision. God’s confirmation to Moses that he was hearing from Him was that after Israel was set free, they would worship Him on the Mount. Not before—after!
Sometimes the Lord speaks to us things that we don’t understand at the time. Often this is to draw us into a deeper understanding of His ways by encouraging us to put other things aside (both things that take up our time, and beliefs and doctrines based on tradition) in order to get the answer from the Lord (not by figuring it out by talking to those who know better or reading every book on the subject).
