“failure to attain a deeply satisfying life always has the effect of making sinful actions seem good. Here lies the strength of temptation…Normally our success in overcoming temptation will be easier if we are basically happy in our lives. To cut off the joys and pleasures associated with our bodily lives and social existence as ‘unspiritual’, then, can actually have the effect of weakening us in our efforts to do what is right.” (Dallas Willard as quoted by John Ortberg in ‘The Life you’ve always wanted’.)
