Wisdom is living well in God’s good, but fallen, world.
I think this is an excellent working definition, but I would like to amend it.
Wisdom is living well in God’s good world, both in the fallen and in the redeemed.
Not quiet as snappy, but I believe that wisdom itself (including the task of wisdom) will be a feature of the renewed earth. In the regeneration (as Jesus calls it in Matt 19:28), the realisation of true wisdom in every person, through the resurrection of bodies totally aligned to the motivation of God’s Spirit (1 Cor 15:44), will be one feature of the life of the new community, with Christ, our wisdom, as the head.
