Both Paul and James agree, we are saved by faith. But as Luther said so well, we are saved by faith alone but the faith that saves, is never alone. It comes with works for that is what genuine faith is.
James chapter 3 is all about the words we use and the impact of these words on our own souls.
James offers us insight into the power of the tongue. He begins by pointing out that human beings have been able to tame every kind of animal but cannot tame the tongue.
As we read through this text it becomes clear that there are two competing wisdoms and we must choose one. It is the choice between earthly wisdom and wisdom that comes from above.
If you rely on the kind of wisdom whose origins come from our world and culture, then devastation will follow.
James makes it clear that many quarrels come about because Christian people are not learning wisdom from God. Instead they have never let go of the wisdom of this world.
What James is showing us in the end of chapter 4 is what pride looks like.
If the rich care only for themselves God will demand it of them in the last day.
James has been fostering attitudes in us. First be patient. Second establish your heart. Third remain steadfast. Persevere by following the example of the heroes of the past.
