The houses we can see stand on a foundation we cannot see. This is how it is in the lives of human beings: we see the body and its five senses with its manifestations, but the real person is what we cannot see: the soul. It represents our feelings, emotions, thoughts, or our will. Everything we see on the outside is only the manifestation of the state of our soul. However, man in general is more concerned with taking care of his body (appearance, food, or clothing) and pays less attention to his soul, which influences his actions and reactions. This book addresses fundamental principles for keeping our soul healthy in order to live fulfilled and balanced lives in all areas. It touches on the family, the fundamental unit of society, starting with the journey of the single person to marriage. It continues with the relationship for a successful marriage. It also leads to committing to a new life with Jesus Christ and following a path of growth. A contrast is made between good and evil, in order to distinguish life according to the world from life according to God. Finally, he concludes with some spiritual laws that support the Christian life.
