Rising Up to Preach the Gospel

What is the meaning of our human life? If we are not here for the preaching of the gospel and saving souls, then what are we here for? You are working so that you can have food to eat, and you have been eating for so many years, yet it is still the same food. What is there to this? If we are not here for the Lord, what is the meaning of our eating? We cannot be the evil and slothful slaves. We must arise to do the work of reaping by actively preaching the gospel.
