God is the Creator and Ruler of the universe.
He has eternally existed as the Father, the Son, and the Holy Spirit. The three are coequal and are one God. (Genesis 1:1, 26, 27, 3:22, Psalm 90:2, Matthew 28:19, 2 Corinthians 13:14)
Jesus is the Son of God.
He is coequal with the Father and Holy Spirit. Jesus lived a sinless human life and offered Himself as the perfect sacrifice for the sins of all people by dying on a cross. He arose from the dead after three days to demonstrate His power over sin and death. He ascended to Heaven and will return again someday to earth to reign as King.
