An optimist sees an opportunity in calamity,
a pessimist sees calamity in every opportunity.
An optimist says his glass in half full,
a pessimist says his glass is half empty.
Optimists count their blessings,
pessimists discount theirs.
To an optimist a fireplace is a center of warmth and beauty.
To the pessimist it is a source of smoke and ashes.
A pessimist seldom recognizes an opportunity
because it usually involves some difficulty.

Persecution of the early Christians provided an opportunity to
spread the good news to the regions of Judea and Samaria.
"…And on that day a great persecution arose against the church in Jerusalem; and they were all scattered throughout the regions of Judea and Samaria…those who had been scattered went about preaching the word."
Acts 8:1,4
The Apostle Paul's arrest turned into an opportunity.
Now I want you to know, brethren, that my circumstances have turned out for the greater progress of the gospel, so that my imprisonment in the cause of Christ has become well known throughout the whole praetorian guard and to everyone else.
Philippians 1:12-13
