See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ. (Colossians 2:8)
Some look for wisdom in psychology. But God's word says psychology is empty. Solomon said the wise dies just like the fool! (Ecclesiastes 2:16b). Man's wisdom is vanity. God's word is sufficient.
Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work. (2 Timothy 3:16-17)
Some look for wisdom in the heart. But the heart is deceitful above all things, and desperately sick; who can understand it? (Jeremiah 17:9)
Some look for wisdom in the world. But God says the world is in the hand of the evil one.
We know that we are from God, and the whole world lies in the power of the evil one. (1 John 5:19)
It is only God's word where we can find the knowledge we need for living in a way that pleases Him. David was declared by God to be a man after His own heart. One reason is that David relied on His word, reveled in His word, and walked in His word. See all the ways David describes God's word:
Blessed are those whose way is blameless,
who walk in the law of the LORD!
Blessed are those who keep his testimonies,
who seek him with their whole heart,
who also do no wrong,
but walk in his ways!
You have commanded your precepts
to be kept diligently.
Oh that my ways may be steadfast
in keeping your statutes!
Then I shall not be put to shame,
having my eyes fixed on all your commandments.
I will praise you with an upright heart,
when I learn your righteous rules.
I will keep your statutes;
do not utterly forsake me! (Psalm 119:1-8)
The Hebrew meaning of each of these different ways David described his delight in God's word:
way: road, distance, journey, (bespeaks a journey from justification to glorification, not just one instance of obedience)
testimonies: spoken word (bespeaks the legal aspect of the LORD's commands for His people)
precepts: A mandate of God; collectively when plural, for the Law, commandment (bespeaks His authority and our obedience)
statutes: something prescribed or owed, a statute, limit or boundary (bespeaks do not go beyond but stay within)
commandments: obligation, terms. (commandments are not suggestions)
rules: ordinance promulgated by, law of Kings (bespeaks the origin of the Law)
Do you read your Bible every day? Are you a woman after God's heart? A man after God's heart?
Where is wisdom? In God and His word.
