That is your duty. And train your children to become like that. The higher nature is already within you. Realise it, control your lower mind and passions for the time being, then you will be able to live on the spiritual plane as the master over sense-pleasures. Realise that the power to save yourself will not come to you unless you have faith in yourself, unless you know that God is within you and unless you become fearless.
Faith brings out the power of the mind.
Faith is always constructive while doubt is destructive. It is an affirmation. You say with full energy that it will be so and it will happen so. But if you vacillate and doubt, you would not be able to reach the highest results. That faith is beneficial which is founded upon right knowledge, right reason and is supported by proper evidence.
