What is my disposition? What is the condition of my heart? “All the days of the oppressed are heavy,” says Proverbs, “but the cheerful heart has a continual feast,” (15:15). The heart of a slave can be timid or pessimistic because she worries that God and the world are laughing at her (Gen. 18:12-15). But a child of promise believes that God and the world are laughing with her (Gen. 21:6) and so she is free from the fear of failure and lives with a disposition of joy, wonder and confidence.
