All the strength and force of man comes from his faith in things unseen.
He who believes is strong; he who doubts is weak.
Strong convictions precede great actions.
It is within my power either to serve God or not to serve him. Serving him,
I add to my own good and the good of the world.
Not serving him,
I forfeit my own good and deprive the world of that good, which was my power to create.
Although the threads of my life have often seemed knotted,
I know, by faith,
that on the other side of the embroidery there is a crown.
An optimist is a person who sees only the lights in the picture,
whereas a pessimist sees only the shadows.
An idealist, however, is one who sees the light and the shadows,
but in addition sees something else:
the possibility of changing the picture,
of making the lights prevail over the shadows.
Felix Adler
