Principles are only tools in the hands of God; they will soon be thrown away when they are no longer useful.

Prayer is the supreme instance of the hidden character of the Christian life.

Only those who obey can believe, and only those who believe can obey.

When our will wholeheartedly enters into the prayer of Christ, then we pray correctly.

Salvation is free, but discipleship will cost you your life

It matters little what form of prayer we adopt or how many words we use. What matters is the faith which lays hold on God, knowing that He knows our needs before we even ask Him. That is what gives Christian prayer its boundless confidence and its joyous certainty.

Must the Christian go around looking for a cross to bear, seeking to suffer? No, insisted Bonhoeffer. Opportunities for bearing crosses will occur along life's way and all that is required is the willingness to act when the time comes. The needs of the neighbor, especially those of the weak and downtrodden, the victimized and the persecuted, the ill and the lonely, will become abundantly evident.
