We all have the power of thought – so what are you lacking? If you have willpower, then you can change anything. It is usually said that you are your own master.
As you are externally aware, so also you can be inwardly aware of your thoughts and feelings, of your motives and urges, of your prejudices, envies, greed and pride…This outward and inward awareness is a unitary process which brings about a total integration of human understanding.
Hope is important because it can make the present moment less difficult to bear. If we believe that tomorrow will be better, we can bear a hardship today.
Be mindful of your duty to God, and do good works; and again, be mindful of your duty, and believe; and once again: be mindful of your duty, and do right. God loves the doers of good.
