Impressions of the Spirit can come in response to urgent prayer or unsolicited when needed. Sometimes the Lord reveals truth to you when you are not actively seeking it, such as when you are in danger and do not know it. However, the Lord will not force you to learn. You must exercise your agency to authorize the Spirit to teach you. As you make this a practice in your life, you will be more perceptive to the feelings that come with spiritual guidance. Then, when that guidance comes, sometimes when you least expect it, you will recognize it more easily.
Richard G. Scott
