Service is a reward, not a punishment. This idea is foreign to people who dislike their work and only put up with it until retirement. We think that faithful work should be rewarded by a vacation for the rest of our lives. But God offers us something very different: more work, more responsibilities, increased opportunities, along with greater abilities, resources, wisdom, and empowerment. We will have sharp minds, strong bodies, clear purpose, and unabated joy. The more we serve Christ now, the greater our capacity will be to serve Him in Heaven.
