What Makes Prayer Effective?
In James 5:16, at the end of the verse, there is a statement made that we talk about quite a bit when it comes to prayer: The effective, fervent prayer of a righteous man avails much.
If you look at these words in the Greek, you will find that effective means “to be active or to be efficient,” and fervent has implications of heat or zeal. So you could say that an active, efficient, hot, zealous prayer avails much, or accomplishes much in the Spirit.
