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.
Charles HodgeIt is because God is infinitely great and good that his glory is the end of all things; and his good pleasure the highest reason for whatever comes to pass. What is man that he should contend with God, or presume that his interests rather than God's glory should be made the final end?
Charles HodgeOur duty, privilege, and security are in believing, not in knowing; in trusting God, and not our own understanding. They are to be pitied who have no more trustworthy teacher than themselves.
