Perseverance is the most important factor considering the spiritual growth in a person. It’s the building block of prayer life. Spiritual growth is in vain if the person lacks perseverance. A person must persevere in his spiritual exercises without break as troubles may grow in every step ahead. It’s an important part in our prayer to include our request to the Lord for giving enough grace so as to persevere till we reach the state of complete union with the Lord of our soul.
