God exists eternally in three persons, Father, Son and Holy Spirit, and each one of them is God and there is only one God. God is Spirit, infinite and immutable in His being, wisdom, power, holiness, justice, goodness, love, truth, perfections/attributes, purposes and promises. He is active, feels emotions and is personal. He interacts with us, and we can relate to Him.
