How far you go in life depends on your being tender with the young, compassionate with the aged, sympathetic with the striving and tolerant of the weak and strong. Because someday in your life you will have been all of these.

To those who have as yet not learned the secret of true happiness, which is the joy of coming into the closest relationship with the Maker and Preserver of all things: begin now to study the little things in your own door yard.

God gave them [the discoveries] to me; how can I sell them to someone else?

Nothing is more beautiful than the loveliness of the woods before sunrise. At no other time have I so sharp an understanding of what God means to do with me as in these hours of dawn.

When I woke the answer was there. Why, then, should we who believe in Christ be so surprised at what God can do with a willing man in a laboratory? Some things must be baffling to the critic who has never been born again.
