The human heart by nature seeks after God. There is a spiritual vacuum in every man until it is filled by Christ.

When an engineer has built a bridge, the fact that a cat can pass over the bridge is no proof that the bridge is good. A train must pass over it to prove its strength.

Whoever wishes to meet Jesus must meet him in places where brothers and sisters of Jesus are hungry, thirsty, naked, unwanted, sick or in prison. Whoever keeps himself distant from these places remains distant from Jesus.

We should never stop at having won a soul for Christ. By this, we have done only half the work. Every soul won for Christ must be made to be a soul-winner.

It was in prison that we found the hope of salvation for the Communists. It was there that we developed a sense of responsibility toward them. It was in being tortured by them that we learned to love them.

I have found truly jubilant Christians only in the Bible, in the Underground Church and in prison.

I had prepared myself for prison and torture as a soldier in peacetime prepares for the hardships of war. I had studied the lives of Christians who had faced similar pains and temptations to surrender and thought how I might adapt their experiences. Many who had not so prepared themselves were crushed by suffering, or deluded into saying what they should not.
