Scripture contains Law and Gospel.
The two relate. They function as a team.
As Luther said, "The Law discovers the disease, The Gospel delivers the remedy."
Even so, they also must be kept distinct.
Many preachers and teachers fail to distinguish them.
That's a terrible problem!
It's why, every day, anxious and despairing Christians ask questions like...
"Am I doing well-enough?"
"Can I ever be sure that I'm saved?"
Long story short, it is life-changing to learn to distinguish The Law and Gospel as Scripture does.
