“The tragedy of this world is not so much the pain in it; the tragedy is that so much of it is wasted. It is only when a log is thrown into the fire that it begins to sing. It is only when the thief was thrown into the fire of a cross that he began to find God. It is only in pain that some begin to discover where love is.”
~ Archbishop Fulton Sheen, Seven Words of Jesus and Mary
As well as this one:
All things work together for the good of those that love the Lord and are called according to his purpose. ~Romans 8:28
Considering that each one of us is called to His purpose, and each one of us is loved by God and called to love Him, this quote is also one to return to again and again in times of suffering.
