what will happen tomorrow (saint francis de sales)

Poetry:
Do not look forward to what might happen tomorrow.
The same Everlasting Father, who cares for you today -
will take care of you tomorrow.
Either He will shield you from suffering,
or He will give you unfailing strength -- to bear it.
Be at peace then,
and put aside all ancious thoughts and imaginations.
[Have Faith - Pray!]
-Saint Francis de Sales
