Before anything else, we must seek out the goal for the creation of human beings which is the highest creature of the world of Creation.
They take a way which is long and full of twists and turns towards God, towards Absolute Perfection, towards spiritual perfection in all dimensions.
Without doubt, this way cannot be taken and the goal cannot be attained without the presence of a pure leader and it is not possible to undertake this way without a leader who is a heavenly teacher because: It is a way full of darkness and the dangers of becoming lost.
It is clear that God created the human beings with their own free will and choice and gave them a conscience and a heavenly book and sent his prophets to them but it is possible that the human being, in spite of all of these facilities and possibilities, err upon the way. Clearly, the presence of an infallible leader will help to prevent the danger of deviation and going astray to a great extent, and in this way, all existence of the Imam is necessary to complete the goal of creation of human beings.
This is that very thing which is called ‘the law of kindness’. What is meant by this is that God, the Wise, has seen to all of the affairs of the human being to reach the goal of creation among which is the sending of the prophets and the selection of pure Imams, otherwise there would be an imperfection in purpose. (Note this carefully).
