In Christianity, the conceptions of God include the following:

1. The Creator: God is the Creator of the universe and all things in it. This is a fundamental belief in Christianity, and is mentioned in the first chapter of the Bible. God created everything out of nothing, and continues to sustain and guide all things in existence.

2. The Triune God: Christianity also teaches that God exists as a Trinity of three persons - Father, Son, and Holy Spirit. This is known as the Christian faith's most distinctive and fundamental dogma, and is mentioned in the Nicene Creed. The three persons are co-equal and co-eternal, yet distinct in their relations and functions.

3. The Son: Jesus Christ is seen as the Son of God, who was incarnate in human form and saved humanity through his life, death, and resurrection. Jesus is central to the Christian faith, and his teachings and example are the basis for Christian morality and devotion.

4. The Holy Spirit: The Holy Spirit is also a conception of God in Christianity. The Holy Spirit is seen as the supernatural force or entity that empowers and guides Christians in their daily lives. The Holy Spirit is believed to be active in every Christian's life, leading them to live a godly life, emboldening them to witness and spread the gospel, and helping them to understand and apply the teachings of the Bible.

These conceptions of God are fundamental to Christian faith and devotion, and are based on the teachings of the Bible and Christian tradition.
