“I suppose that in many ways it can truthfully be said that the greatest need of men and women in this world is the need of what is called a quiet heart, a heart at leisure with itself.
Is that not, in the last analysis, the thing for which we are all looking? You can if you like call it peace; that means exactly the same thing, peace of mind and peace of heart, tranquility. We are all restless; we are all disturbed. There is unhappiness in us. . . .
[I]t is not only the Christian gospel that offers us freedom from the troubled heart. There are many ways in which we are exhorted to try to find this peace. . . .
The claim of the gospel is not only that it can give us a quiet heart, but also that nothing else can do it.”
–Martyn Lloyd-Jones, Let Not Your Heart Be Troubled (Crossway, 2009), 16-18
