Half-hearted Christianity!

(Horatius Bonar)

If you are Christians, be consistent. Be Christians out and out — Christians every hour, in every part. Beware . . .
  of half-hearted discipleship,
  of compromise with evil,
  of conformity to the world,
  of trying to serve two masters,
  of trying to walk in two ways, the narrow and the broad, at once.
It will not do. Half-hearted Christianity will only dishonor God, while it makes you miserable!

"No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and Money!" Matthew 6:24
