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

Every Christian must be fully Christian by bringing God into his whole life, not merely into some spiritual realm.

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.

I can no longer condemn or hate a brother for whom I pray, no matter how much trouble he causes me.

God loves human beings. God loves the world. Not an ideal human, but human beings as they are; not an ideal world, but the real world. What we find repulsive in their opposition to God, what we shrink back from with pain and hostility, namely, real human beings, the real world, this is for God the ground of unfathomable love.

Cheap grace is grace without discipleship, grace without the cross, grace without Jesus Christ, living and incarnate.

The best-informed man is not necessarily the wisest. Indeed there is a danger that precisely in the multiplicity of his knowledge he will lose sight of what is essential.
