Never let the thought of weakness enter your consciousness, but always ignore the suggestion and affirm yourself to be a tower of strength, within and without. The development of man is under law. Creative Mind is not only law, but it is governed by the action of the law that it sets up. Man's development is not primarily under the physical law, because the physical law is secondary. There is a law of Spirit, and the earthly is but the showing forth of some of the results of that law.
Evolution is the result of the development of ideas in mind.
What we are is the result of the evolution of our consciousness, and that consciousness is the result of seed ideas sown in our mind. When Froebel, the great teacher of children, began his primary school, he thought a long time before he gave it a name. Humanity is the garden of God, of which the soil is the omnipresent thought substance. If you will to do the will of God, the exercise of your will in God-Mind strengthens your will power. If you have faith in things invisible, the faith seed is growing in your mind and your faith will be increased.
