Never, in peace or war, commit your virtue or your happiness to the future. Happy work is best done by the man who takes his long-term plans somewhat lightly and works from moment to moment 'as to the Lord.' It is only our daily bread that we are encouraged to ask for. The present is the only time in which any duty can be done or any grace received.
C. S. LewisWe forgive, we mortify our resentment; a week later some chain of thought carries us back to the original offence and we discover the old resentment blazing away as if nothing had been done about it at all. We need to forgive our brother seventy times seven not only for 490 offences but for one offence.
C. S. LewisThe human heart is not unchanging (nay, changes almost out of recognition in the twinkling of an eye).
