A canker into the very core of your spirituality!

(Octavius Winslow, "Evening Thoughts")

"Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind." Romans 12:2

Heavenly-mindedness can only be maintained by the strictest vigilance. It is a delicate and fragile flower, susceptible of every variation of the spiritual atmosphere. Guard against that which checks its growth.

Many are not aware how much . . . 
  great joviality,
  light conversation,
  foolish jesting,
  novel reading,
  carnal music,
unfit the heart for communion with God, and lessen the tone of its spirituality.

Close communion with mere nominal religious professors is particularly to be avoided. Much more injury to spiritual-mindedness accrues from intimate friendship with such, than from those who assert no pretensions to a religious character; as with the one we are apt to be less on our guard than the other.

Avoid the world's amusements they will eat as a canker into the very core of your spirituality!

"Do not conform any longer to the pattern of this world" is a prohibition which should never be absent from the eye of a traveler to the heavenly city.

Are not heaven's attractions many and powerful?

How rich is heaven! Why, then, should not our thoughts be there? Oh! shall not our hearts be more where our most precious treasure is, where our holiest and dearest hopes center, and where we ourselves shall shortly be?
