How can we live a truly satisfying and happy life?

We can live a truly satisfying and happy life, if we are focusing our life on the service for Jehovah God. Why?

Because then our life is not in the least futile. We can read in God’s word, the Bible: “(1 Corinthians 15:58) Therefore, my beloved brothers, be steadfast, immovable, always having plenty to do in the work of the Lord, knowing that your labor is not in vain in connection with the Lord.”
