Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance. Let perseverance finish its work so that you may be mature and complete, not lacking anything. If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. That person should not expect to receive anything from the Lord. Such a person is double-minded and unstable in all they do.
When we’re in the pressure cooker, it’s easy to revert to something less than helpful. We need something better than fight or flight. And James gives us something much better here.
We’re to count it all joy when any given trial hits us, because through that God can do a deeper work in us. We need to persevere through it, so that we can grow in whatever way God has for us.
I think we can connect that with the directive to ask God for needed wisdom. Maybe it can stand alone as well, since James is more like Proverbs than any other book in the New Testament. Either way, it only makes sense to ask God for wisdom in trials. God will give it to us as we go on imperfectly as it will be, with a heart set on living in his will. In and through Jesus.
