“We suffer more often in imagination than in reality.”
Seneca, Letters to Lucilius, 13 (public domain)
Matthew 6:34 WEB
Therefore don’t be anxious for tomorrow, for tomorrow will be anxious for itself. Each day’s own evil is sufficient.
Most of the weight we carry never arrives. We rehearse the worst case, then live the rehearsal instead of the day in front of us.
Seneca names the habit. Jesus puts a fence around it: tomorrow has its own trouble. Today has enough work, enough mercy, and enough obedience without borrowing the next morning’s fear.
Do the next honest thing. Pray the next short prayer. Leave the rest on the hook until it is actually here.
