God's wisdom is not first counsel on how to practice family values or to use common sense. It is the wisdom of His plan of grace, the wisdom of the Cross. That wisdom is foolishness to the calculations of prudence. Wise living is sacrificial living, giving up what it cannot keep to gain what it cannot lose [to quote Jim Elliot]. It is a thank-offering of praise, enabled by the mercy of God that has united us to Christ in His death and resurrection.
