If you have once accepted Christianity, then some of its main doctrines shall be deliberately held before your mind for some time every day. That is why daily prayers and religious reading and churchgoing are necessary parts of the Christian life. We have to be continually reminded of what we believe. Neither this belief nor any other will automatically remain alive in the mind. It must be fed.
C. S. LewisTo make Christianity a private affair while banishing all privacy is to relegate it to the rainbow's end or the Greek Calends.
C. S. LewisFallen man is not simply an imperfect creature who needs improvement: he is a rebel who must lay down his arms. Laying down your arms, surrendering, saying you are sorry, realizing that you have been on the wrong track and getting ready to start life over again from the ground floor-that is the only way out of a "hole." This process of surrender-this movement full speed astern-is repentance.
C. S. Lewis
