Touch
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.
Ésaïe 40:5-8
5
Alors la gloire de l'Eternel sera révélée, Et au même instant toute chair la verra; Car la bouche de l'Eternel a parlé.
6
Une voix dit: Crie! -Et il répond: Que crierai-je? Toute chair est comme l'herbe, Et tout son éclat comme la fleur des champs.
7
L'herbe sèche, la fleur tombe, Quand le vent de l'Eternel souffle dessus. -Certainement le peuple est comme l'herbe:
8
L'herbe sèche, la fleur tombe; Mais la parole de notre Dieu subsiste éternellement.
