There is one living and true God (Deuteronomy 6:4; Jeremiah 10:10; 1Corinthians 8:4-6; 1Thessalonians 1:9) who exists in three distinct Persons—Father, Son and Holy Spirit (Matthew 28:19; 2Corinthians 13:14). Each Person is fully God, yet the Godhead is one and indivisible (Exodus 3:14; John 14:11; 1Corinthians 8:6; Acts 5:3-4; 1Corinthians 3:16-17). God is sovereign and works all things according to his own righteous will, for his own glory (Romans 11:33-36).
From all eternity God decreed everything that would ever happen in time (Proverbs 16:4; Isaiah 46:10; Ephesians 1:11b; Romans 11:33-34; Revelation 15:3-4). God has revealed himself generally to all people in creation, in providence, and in their inner consciousness and conscience. This revelation does not lead to a saving knowledge of God but does leave people without excuse for their failure to glorify him as God and to give him thanks (Psalm 19:1-6; Romans 1:19-21; 2:14-15).
