James 3: 13-18
Wisdom is divided into two realms—man’s and God’s, earthly and heavenly.
The kind of wisdom a person posses will be revealed by the kind of life he lives. Those who possess the wisdom of man will demonstrate by their lives that they have no relationship with Jesus Christ and no desire to worship, serve, or obey Him. On the other hand, those who possess genuine faith will manifest the wisdom of God, the wisdom from above.
Broadly defined, wisdom is not simply a matter of possessing factual knowledge but of properly and effectively applying truth to everyday life.
True wisdom was not intellectual but behavioural. Thus the biggest fool was one who knew the truth and failed to apply it. To the Jews, wisdom meant skill in living righteously.
In conclusion, if a person professes faith in Jesus Christ and claims to have wisdom from God, but has a heart that is proud, arrogant, and self-centred and lives a life that is worldly, sensual, and self-serving, his claims to salvation are false.
