From “Discipleship and Discipline” by William H. Hicks, copyright March, 2005:
“Paul emphasizes the importance of intercessory prayer to the discipling process in Ephesians 6. In verse 18 – 19, he writes, “With all prayer and petition, pray at all times in the Spirit, and with this in view, be on the alert with all perseverance and petition for all the saints, and pray on my behalf, that utterance may be given me in the opening of my mouth, to make known with boldness the mystery of the gospel,…”
It is clear that disciples should pray for those who spread the gospel. There is the clear, emphatic affirmation that prayer is not easy. Most of us think nothing of falling on our knees before God and praying- until we get there! When Paul says that we should “be on the alert with all perseverance”, it becomes apparent that prayer can be a battle and being “on your knees” becomes a “theater of operations”- a military term which describes the field of battle, of major conflict.”
