If I have any worth, it is to live my life for God...

If I be worthy, I live for my God to teach the heathen, even though they may despise me.

No one should ever say that it was my ignorance if I did or showed forth anything however small according to God's good pleasure but let this be your conclusion and let it so be thought, that - as is the perfect truth - it was the gift of God.

Many believe - and I believe - that I have been designated for this work by God. In spite of my old age, I do not want to give it up I work out of love for God and I put all my hope in Him.

I wanted to be a teacher. I love children, so I wanted to deal with children. Then I wanted to be a veterinarian. But by the age of ten or eleven, when I opened my mouth and said, 'Oh, God, what's this?' I kind of knew teaching and being a veterinarian were gonna have to wait.

The face you have at age 25 is the face God gave you, but the face you have after 50 is the face you earned.

It's really amazing that in the age of unbelief, as a smart man called it, there isn't even more fraud. After all, with no God, there's no one to ever call you to account, and no accounting at all if you can get away with it.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.
