The Bible may be an imperfect guide written by imperfect men but I believe we all can find passages that provide comfort in guidance somewhere within the pages of the Good Book. Being an Old Testament man I have found a guide to the spiritual existence in Ecclesiastes.
Ecclesiastes 8:15. “I therefore praised enjoyment. For the only good a man can have under the sun is to eat and drink and enjoy himself.” (“Enjoy himself” has also been often translated as “be merry.”)
Who can argue with that?
