In a traditional worldview and anthropology, weakness (astheneia) is a bad thing that should be overcome.
This world is a shaky one full of weakness.
It has once been a perfect place as in Eden.
But it became a place of punishment because of human sin.
This world needs a final redemption.
In a final recovery of creation, weakness would be no more, tears no more, and death no more.
Likewise, humanity has once been perfect without sins.
At that time there was neither weakness nor death.
But because of sin, humanity was destined to die.
But there is an alternative view which I argue for.
That is, weakness is embedded in the world. It is not the result of human sin.
Likewise, weakness imbues human beings from the beginning.
Even in the creation story of Gen 2, it is implied that weakness is part of God's forming of first human Adam. It is because of adama (ground) that is part of Adam. Adama is the dust to which humans return.
Weakness is a human condition that we have to live with. It is not something we can transcend.
We have to learn how to get along with it.
We have to learn its implication to our life.
Perhaps we can see others, ourselves, and the world from a different perspective of weakness -- an eye of humility and solidarity.
If I am weak, others are also weak.
Because I am weak, hope is not within or from me.
In this regard, weakness can be a virtue, as Paul says that "when I am weak, I am strong" (2 Cor 12: 9-11).
