Martyn Lloyd-Jones
I never find Jesus Christ changing His Gospel in order to make it suit the people. I find Him changing the people in order to make them fit into His Gospel.

Poor souls are apt to think that all those whom they read or hear of to be gone to heaven, went there because they were so good and holy. Yet not one of them, not any one that is now in heaven (Jesus Christ alone excepted), did ever come there any other way but by forgiveness of sins.
John Owen
