According to James, effective prayer is that which is offered
Answer Details
James, in the Bible, teaches that effective prayer is that which is offered in faith. This means that when we pray, we must have a strong belief and trust in God that He will answer our prayers. We must have faith that He hears us and that He is able to do what we ask of Him.
Prayer with emotion, whether loud or silent, may indicate sincerity and intensity of our feelings, but it is not the determining factor of its effectiveness. Effective prayer is not about how loudly or passionately we pray, but rather, it is about the attitude of our hearts and the strength of our faith in God.
Therefore, the correct answer is: "in faith."
