Mike Bickle emphasizes the transformative power of effective prayer, sharing his personal journey from disdain to enjoyment of prayer. He highlights that prayer is not only about relationship with God but also about achieving results, as seen in the teachings of Jesus and the example of Elijah. Bickle outlines four key characteristics of effective prayer: rooted in faith, grounded in good relationships, stemming from a lifestyle of righteousness, and earnestness. He encourages believers to understand that their prayers can have lasting impacts beyond immediate results, reinforcing the idea that every believer can access God's power through sincere prayer.

Charles Finney emphasizes the vital role of the Holy Spirit in prayer, explaining how the Spirit intercedes for believers, helping them to pray according to God's will, especially in times of ignorance about what to pray for. He outlines the nature of the Holy Spirit's influence, the necessity of fervent prayer, and the importance of recognizing and not grieving the Spirit. Finney encourages believers to seek the Spirit's guidance actively and to maintain a deep awareness of the spiritual state of themselves and others, as this leads to effective prayer and a fruitful Christian life.
