Acts 14: Why is Paul motivated to share the Gospel?

Why was Paul motivated to go out and share the gospel with the world? Why should we be motivated to give our lives to share the gospel with the world? The future is what should motivate us, this life on earth is only the beginning. Just as we see in our world, Paul also experienced persecution, problems and pressure, but he persevered. He persevered because he knew the future that awaiting us is worth it.
