The document discusses how Christians can fulfill God's command to be united. It provides 4 D's for achieving unity: 1) Devote ourselves to others through continuous, intentional love; 2) Dedicate towards the same purpose through unity in diversity; 3) Denounce selfishness by considering others better than ourselves through humility; 4) Desire the interest of others more than our own by regarding others' interests as our own. The Tower of Babel story shows how powerful unity can be when united for the right reasons, and Christians ought to pursue unity as Christ laid down his life to make it possible.
