Throughout this letter, James has placed no small emphasis upon the way we use our tongues. So it serves as no surprise that as he winds down-wraps up, he exhorts us unto its highest use- prayer, praise - persuading others unto godliness. But the primary emphasis of this passage -by far- is placed upon prayer -being mentioned 7x's in Vs 13-18-. He exhorts us to pray over our suffering, to seek prayer in times of sickness, we're to pray - intercede for one another- - we are to pray fervently. Meaning, not hyper-emotionally, - not mechanically or absent mindedly, but sincerely, passionately, from the heart.
