Where possible Paul avoids quoting the teaching of Jesus, in fact even mentioning it. If we had to rely on Paul, we should not know that Jesus taught in parables, had delivered the sermon on the mount, and had taught His disciples the 'Our Father.' Even where they are specially relevant, Paul passes over the words of the Lord.

If you study life deeply, its profundity will seize you suddenly with dizziness.

The only thing of importance, when we depart, will be the traces of love we have left behind.

Does my behavior in respect of love affect nothing? That is because there is not enough love in me.

We cannot possibly let ourselves get frozen into regarding everyone we do not know as an absolute stranger.

Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly if they even roll a few more on it. A strength which becomes clearer and stronger through experiences of such obstacles is the only strength that can conquer them. Resistance is only a waste of strength.

Let your life be your argument.
