Because I am a part of the Big Picture, I do matter and substantially so. Because I am only a part, however, I am rightly situated off to stage right—and happily so. What freedom there is in such truth! We are inherently important and included, yet not burdened with manufacturing or sustaining that private importance. Our dignity is given by God, and we are freed from ourselves!
Foolish talking and jesting are not the ways in which Christian cheerfulness should express itself, but rather "giving of thanks" (Eph. 5:4). Religion is the source of joy and gladness, but its joy is expressed in a religious way, in thanksgiving and praise.
