We see that Christian life, far from being a complicated observing of a thousand rules, is something infinitely simple: to do everything for God’s love. At every second of our life all our thoughts and words, all our actions must be done for the love of God. At any moment, if someone asked us the motive of our actions, we should be able to answer: ‘the love of God’.
All which is not for God’s love, however, is `vanity of vanities’; every second which is not a loving motion towards God is worthless.
