The Bible guides Seventh-day Adventists in their Christian lives by teaching beliefs they are expected to follow and teach others. This includes the belief in the Trinity as described in passages like Ephesians 4:4-6 and Deuteronomy 6:4, which state there is one God who exists as the Father, Son, and Holy Spirit. Adventists are to apply these biblical beliefs to their lives and set a positive example for future generations.
