How can you complain about life if you don't pray? How can you be angry with God when you don't speak to Him, or, more importantly, listen to Him? The time has come to elevate your life. The only way to do this is by communicating with God, which is prayer.
The great saint tells us:
"Prayer is the exaltation of the nous* and the heart to God, so they can give glory and thanks to Him."
- St. Theophan the Recluse
* For the Orthodox Christian, the nous is often called the eye of the soul. It is the internal faculty of the human, which validates true spiritual knowledge.
