An adverse wind…

They who set out to sail unfurl the sails at first when they encounter a favorable wind but then undo it when an adverse wind comes at them; the sailors do not discharge the ship because the wind is against them. They wait quietly for a while or wrestle with the storm, then they sail on again. So it is with us; when an adverse wind is against us, let us complete our voyage without fear, having unfurled the cross instead of a sail.
–Saint Synkletike (a Desert Mother) (d. 350)

Endure present troubles…

He who wishes to avoid future troubles should endure his present troubles gladly. For in this way, balancing the one against the other, through small sufferings he will avoid those which are great.
–Saint Mark the Ascetic (Fifth Century)
