In the framework of these few verses we have learned a great deal. Wisdom was a topic that could have been the subject of its own book, but the important things to remember are that true wisdom comes from God, He gives generously, and He gives without prejudice.
We learned about how to make requests of God and about requesting wisdom in particular. This led to discussing the chief requirement made of us when asking for wisdom (or anything else from God), which is faith. James explains to us the nature of doubt and its impact on requests made of God, even for something as basic and as freely available as God’s wisdom.
Faith is also the absolute requirement of salvation (Jn 3:16), though we now know faith is more than mere acknowledgment or even head knowledge. It takes substance in the form of behaviors based on core beliefs and values.
Worry distracts, making it easy to doubt. Doubt leads to susceptibility to temptation, temptation to desire, desire to sin, and sin to death. The vaccine for this process is faith.
