Wrongly Applying Right Doctrine

A helpful reminder from J.I. Packer about wrongly applying right doctrine:

...a ministry which is wholly concerned with gospel truths can still go wrong by giving those truths an inaccurate application. Scripture is full of truth that will heal souls, just as a pharmacy is stocked with remedies for bodily disorders; but in both cases a misapplication of what, rightly used, will heal, will have a disastrous effect. If, instead of dabbing iodine on, you drink it, the effect will be the reverse of curative! And the doctrines of new birth and new life can be misapplied too, with unhappy results.

--Quoted in Knowing God, J.I. Packer
