To achieve the greatest happiness, we must put God first in our lives. Take a married couple. If the husband and wife love each other, but put each other ahead of God, they cannot always be happy. They may get along most of the time, but there will be conflicts. If they both can put God first, then they will experience the closest possible union between a man and a woman on earth. As Fr. Groeschel says in his book Healing the Original Wound, the biggest and most persistent enemy is always self ~ you can never escape yourself; you can only change yourself. By letting God be first in your life, the problem no longer exists.
