Imagine having your mother touch your cheek. Then imagine having your spouse or someone you love romantically touch your cheek. Then imagine having a baby touch your cheek. Then imagine having someone you hate and fear touch your cheek. They're very different feelings, aren't they? They all involve the same nerve endings, stimulated in basically the same ways, but with emotional content that varies to every point of the compass. This is because the sense of touch communicates and actually conveys emotion, communicates and conveys love (both good and bad) between people. That's why the Lord so often touched people as a way of healing them; through touch he could convey His love, which is life itself, to the people he touched. It's also why the people of Israel were not to touch the Ark of the Covenant -- their base loves would be conveyed to the holiness represented by the Ark.

Hands in the Bible represent power, the force with which things are put into action. To be specific, they represent the power of spiritual good -- which is the love of others and serving others -- expressed through spiritual truth -- which is an understanding and knowledge of what it is to love and serve others. This is in contrast to the feet, which represent power on the natural level, and a “rod,” which represents the power of the hand passed down into external or natural ideas. In a few cases in the Bible, hands also represent communication and a drawing together. This is true when people lift their hands to heaven or to Jehovah, and also when the Lord touches children or touches people to heal them.
