Our vocation is not simply to be, but to work together with God in the creation of our own life, our own identity, our own destiny…. This means to say that we should not passively exist, but actively participate in God’s creative freedom, in our own lives, and in the lives of others, by choosing the truth. To put it better, we are even called to share with God the work of creating the truth of our identity….
It demands close attention to reality at every moment, and great fidelity to God as God reveals himself, obscurely, in the mystery of each new situation. We do not know clearly beforehand what the result of this work will be. The secret of my full identity is hidden in God. God alone can make me who I am, or rather who I will be when at last I fully begin to be. But unless I desire this identity and work to find it with God and in God, the work will never be done. The way of doing it is a secret I can learn from no one else but God.
