The sin of prayerlessness as one of the deepest roots of the evil. Few can plead themselves free from this. Nothing so reveals the defective spiritual life in a pastor and the congregation as the lack of believing and unceasing prayer. Prayer is indeed the very pulse of the spiritual life. It is the great means of bringing to a pastor and the people the blessing and power of heaven. Persevering and believing prayer means a strong and abundant spiritual life.
