Law / Gospel Distinction: Sermon 3 (A Little Leaven...)

In this video, Presbyterian author Monty Collier explains that a little bit of leaven (Law) leavens the whole (transforms the Gospel into a law-book). This Biblical analogy is very important. It shows the reason we must keep Law separated from the Gospel, as far as East is from West, as far as heaven is from hell—especially when it come to justification before God.
