The Bible tells us that in this life and world there is no such thing as final security apart from the message of the gospel.

So if we are relying for our final, ultimate happiness upon anybody or anything in this world alone, then we are certain to be disappointed. If our quietness of heart depends--oh, let me put it with almost brutal realism--if we are depending for happiness and joy and a quiet heart, in a final sense, upon any individual human being, upon our family, our home, our profession, our money, our health and strength, we are doomed to experience disappointment.

Every one of these things one day will be taken from us.

--Martyn Lloyd-Jones, Let Not Your Heart Be Troubled (Crossway, 2009), 68
