"Life work" means that to which one will devote one's energies. It is the world of the soul, as well as the material work done in the visible world. These categories of tasks are not separate: they are not inimical to one another any more than sweeping the temple, washing the vestments, or cleaning and arranging the altar are inimical to the act of prayer. On the contrary, these tasks are prayer. They are the work of the soul in that they provide a suitable atmosphere for the cultivation of a contemplative and receptive attitude.
As we are filled ever more deeply with the Spirit, we become more confident in God's abundant love for us.
There is always a way to extend our love depending on the situation and what is appropriate, and by doing that you'll make a difference. Start small. Rather than trying to love the human race, love whom you love, love what you love, and express that. This will draw creativity out of you and will lead you to the next step. Gradually your capacity to love deepens and becomes more universal. Start where you are.
