'Reason' in the Bible

For this reason I have sent to you Timothy, who is my beloved and faithful child in the Lord, and he will remind you of my ways which are in Christ, just as I teach everywhere in every church.

For this reason many among you are weak and sick, and a number sleep.

If the foot says, “Because I am not a hand, I am not a part of the body,” it is not for this reason any the less a part of the body.

And if the ear says, “Because I am not an eye, I am not a part of the body,” it is not for this reason any the less a part of the body.

When I was a child, I used to speak like a child, think like a child, reason like a child; when I became a man, I did away with childish things.
