Prayer as duty is drudgery, but prayer as delight becomes a dynamic encounter with the living God. The desire to pray is not something we work up in our flesh. Ask the Holy Spirit to plant the desire in your heart to pray. A prayerless Christian is a powerless Christian. Why Prayer Fails Unconfessed sin.
Sin is a hindrance to answered prayer.
Not asking according to God's will. Asking with faith that doubts. Improper attitudes toward one's spouse. Idols in one's life. This type of prayer is that of needs, results, and desires.
