SDA Belief No.8 - The Great Controversy:
All humanity is now involved in a great controversy between Christ and Satan regarding the character of God, His law, and His sovereignty over the universe.

This conflict originated in heaven when a created being, endowed with freedom of choice, in self-exaltation became Satan, God's adversary, and led into rebellion a portion of the angels. He introduced the spirit of rebellion into this world when he led Adam and Eve into sin.

This human sin resulted in the distortion of the image of God in humanity, the disordering of the created world, and its eventual devastation at the time of the worldwide flood. Observed by the whole creation, this world became the arena of the universal conflict, out of which the God of love will ultimately be vindicated.

To assist His people in this controversy, Christ sends the Holy Spirit and the loyal angels to guide, protect, and sustain them in the way of salvation.
