As you can see, each of the ten MAS, (mental attitude sins), promote each other. Indeed, it does form a chain of misery and loss. The purpose of this life is not happiness, but the knowledge of God takes supremacy over the details of life.
Because God does exist, His existence does not imply that man’s purpose is happiness apart from His system of protocol. Happiness is, “Eudiamonia.” It is not satisfaction derived from pleasure, but rather it is an aspect of well-being, of excellence and skill of life. These three must have a mentor to teach and operate under God’s plan for man. The mentor is the, Holy Spirit.
“But the comforter, which is the Holy Ghost, whom the Father will send in my name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.“ John 14:26.
