There is one true God. He is almighty and eternal.
God eternally exists in three persons: Father, Son, and Holy Spirit. Each have distinct personal attributes, but together they are one God. (Genesis 1; John 14; Ephesians 1)
Jesus Christ is 100% Man and 100% God. He was born of the virgin Mary, lived a sinless life, died on the cross and rose from the grave. His sacrifice on the cross is the only way for our sin to be forgiven and for us to have a relationship with God. (John 1:1-5; 12-14)
The Holy Spirit is God who lives within the Christian upon belief in Christ. He empowers the Christian to live a godly life and comforts in times of sorrow. (Ephesians 1:13-14; John 14:16-17)
