‘Christ is made unto us wisdom, sanctification and redemption’. ‘As the Scriptures say, he who is proud let him be proud of the Lord’. We need wisdom, It is Christ. Of course this is Spiritual wisdom and not natural. He redeemed us by His blood. He set us part by His blood. His sacrifice on the cross guarantees us wisdom and it is He Himself, He who is within us. James says ‘If anyone lacks wisdom let him ask of God who hands it out freely without a fuss’. Source.
