Misunderstanding when preaching the gospel

Today, I am sharing a longer quote from D. Martyn Lloyd Jones that was in The Naked Gospel by Andrew Farley.

There is no better test as to whether a man is really preaching the New Testament gospel of salvation than this, that some people might misunderstand it and misinterpret it to mean that it really amounts to this, that because you are saved by grace alone it does not matter at all what you do; you can go on sinning as much as you like because it will redound all the more to the glory of grace. If my preaching and presentation of the gospel of salvation does not expose it to that misunderstanding, then it is not the gospel . . . There is this kind of dangerous element about the true presentation of the doctrine of salvation.
