BECOMING A SON/DAUGHTER OF GOD
There is more to it than abstaining from obvious sins like lying, though that is a major part of it. It takes power: Power given by Jesus to those who believe the message of the apostles about Him and believe their records of His words. Hold to these teachings. Especially seek those who proclaim them to you faithfully. If you love Jesus you will not discard the lessons you learn from Him but you will let them build up and create a picture of truth within you, believing that God sent Him, and God calls Him His beloved Son.
