Christian happiness
These are apparently the points from Jonathan Edwards’s first sermon, preached when he had just turned 18 years old.
Why should Christians be happy:
1. Our bad things will turn out for good. Romans 8:28
2. Our good things can never be taken away from us: the light of his countenance, pardon for sin, assurance of grace, the inheritance of eternal life.
3. The best things are yet to come.
From a leadership training session on Personal Prayer by Tim Keller.
