Gratitude can be a vaccine that can prevent the invasion of a disgruntled attitude. (Clinton C. Cox, late preacher)
A lot of people seem to be unhappy, down-hearted and negative much the time. Why is that? Are their circumstances really that different from the rest of the world? Maybe they just need an attitude adjustment. Developing and maintaining an attitude of gratitude will go a long way toward a happy disposition.
Everything God created is good, and nothing is to be rejected if it is received with thanksgiving (1 Timothy 4:4).
