Be at peace then and put aside all useless thoughts …
The fear of some future suffering is greater than the suffering itself. That’s because when we are anticipating the future, we are not yet being given the grace that God will give at that moment.
Here’s how St. Francis de Sales puts it:
Do not look forward to the trials and crosses of this life and fear. Rather, look to them with full confidence that, as they arise, God, to whom you belong, will deliver you from them.
He has guided and guarded you this far in life. Do you but hold fast to His hand, and he will lead you safely through all trials. Whenever you cannot stand, he will carry you lovingly in his arms.
Do not look forward to what may happen tomorrow. The same Eternal Father who cares for you today will take good care of you tomorrow and every day of your life. Either He will shield you from suffering or He will give you the unfailing strength to bear it.
Be at peace then and put aside all useless thoughts, vain dreads, and anxious imaginations.
