The serpent was and is said to be the worst crafty of all the wild creatures that Yahweh God had made. We hear sayings such as “slippery as a snake”, signifying how mischievous an individual can be.
Answering the call of God does not mean that each day for every minute we lie prostrate before him. But and more importantly it means serving others thereby providing them with the necessary freedom they require.
Our existence comes from him and we are dependent on him for survival. Though we may look to others for our needs it is only God who satisfies us. When we answer the call of God he actively take over our lives. He reveals himself to us as the the only truth who creates us and is responsible for us.
