The loss of God results in all the terrors and troubles of this life. Therefore, it is a restored relationship to God that our “happiness” consists:
GOD having framed man an understanding creature, hath made him fit to have communion and intercourse with himself; because he can by his understanding discern that there is a better good out of himself, in communion and fellowship with which, happiness consists. Other creatures—wanting understanding to discern a better good out of than in themselves, their life being their good—desire only the continuance of their own being, without society and fellowship with others. But man, having the knowledge of God, the Creator of heaven and earth, but especially of God the Redeemer, providing for him a second being better than his first, understandeth that his best and chiefest good dependeth more in him than in himself; and because his happiness standeth in acquaintance and fellowship with this God, which is the chief good, he desireth a communion with him, that he may partake of his good.

Imagine it this way: a small child wanders into the forrest alone is not injured by the loss of his father, but his father’s absence is the ultimate cause of his loss. Conversely, the child finding his father does not directly make the forrest less dark, the wolves less dangerous, the night less cold. But return of the father makes it possible to be rescued from all these things.
