Christianity is God's offer of eternal and divine life as his Son or Daughter, dwelling in a loving and creative heavenly society that potentially includes our family and friends, and Jesus Christ.
Jesus Christ is the Son of God who was fully divine as a spirit, then was born as a man. By dying and resurrecting, he made it possible for all Men to become divine like him.
Jesus Christ made this as easy as possible. You merely need to accept his offer and keep on striving to become like him. You don't even need to follow his rules; you merely need to acknowledge that his rules are good and true, and that you ought to follow them - but have not fully succeeded.
In a nutshell, we are already partly divine and can, if we wish, become fully gods after death and within Our Father's heavenly universe - by following the path made for us by our divine brother Jesus Christ.
