Answer 3

This world is a purposeful creation by God, in which all people are tested concerning their use of free-will. We possess a soul which lives on after the body dies and is held responsible for the person's actions. Anyone who is worthy can merit reward in the afterlife.

Also:
1. God exists, and is the Creator.
This tells us that the world is not chaotic or the result of chance. Life is the work of a deliberate, purposeful, intelligent and kind Creator; not a melancholy chaos or a string of fortuitous accidents. God is at the center of reality and the center of our world-outlook and thoughts.
2. God is eternal.
This includes the belief that God's ways are also eternal. God is not capricious, forgetful or fickle.
God is just (Deuteronomy 32:4); and all outstanding accounts are settled after this life.
