Sin of prayerlessness

Prayerlessness is a reproach to God, it is the cause of a deficient spiritual life, the church suffers a dreadful loss as a result of prayerlessness of the minister. what is it that makes prayerlessness such a great sin? At first it looked upon as a weakness, there is so much talk about lack of time and all sorts of distractions that the deep guilt of the situation is not recognized. Let it be our honest desire that in the future, the sin of prayerlessness maybe to us truly sinful.(AM)
