I suffered the same feelings for years until I had life-changing spiritual experiences. Over the past 79 years, I have found that we go through cycles in our spiritual growth, from a Spiritual Springtime to Summer, to Fall, and to a Spiritual Winter.
If we continue to pray and spiritual struggle during our Spritual Wintertime, we will find ourselves at a new level of Spiritual Springtime and Rebirth. The key is learning to stay in your Spiritual Springtime and Summer as much as possible.
