What is True Happiness?

‎"Don’t tell me of your happiness if it daily depends on the uncertainties of the earth. Your home may be rich in comforts; your family may be all you could desire; your income may be amply sufficient to meet all your wants. But oh, remember, if you have nothing more than this to look to, that you are standing on the edge of a cliff! Your joy may be deep and earnest, but it is fearfully short-lived. It has no root. It is not true happiness." ~ J.C. Ryle
