So, now you know the question.
You know the God with whom you are speaking.
You know yourself a bit and what is holding you back.
All of these things will need to be revisited over and over and over throughout the process, so, even though we move on, do not leave them behind. It may take time to really pin down the question - or as you move on, you may find that you need to go back and be more specific. That's fine.
There is no right way to do this. If you need more time on any one step, take it. At the same time, though, don't loiter. If you have some basic clarity, feel free to move forward. You can always cycle back through as necessary.
Now for the training. Discernment is a process, a preparation, a work out.
Have you ever heard of spiritual exercises?
Jogging, weight lifting, sit ups help the physical athlete to prepare, to build muscle, to become strong enough to win the race. You are going to practice building spiritual muscle. And run the race to holiness with strength and endurance.
