The word “God” refers to the being who created, rules, and judges the universe. God’s name in Hebrew is Yahweh (see: Exodus 3:13-14; Isaiah 42:8). This name sounds like the Hebrew word that is translated as “I am.” He is the one and only God. God exists without the help of anything else.
God the Father, Son, and Holy Spirit are different persons of the same being (see: Matthew 28:19-20; Luke 3:21-22; 2 Corinthians 13:14). Jesus is God who became a man (see: John 1:1, 14). The Holy Spirit is also called God (see: Acts 5:3, 4). God is holy (see: Isaiah 6:3), eternal (see: Psalm 90:1-2), unchangeable (see: Malachi 3:6; James 1:17), love (see: 1 John 4:8), and true (see: John 17:17; Titus 1:2; Hebrews 6:18). God is also compassionate, merciful, forgiving, and just (see: Exodus 34:6-7).
God created the universe by Jesus the Son (see: Genesis 1; Jeremiah 10:12; John 1; Colossians 1:16). God also rules over everything because he owns everything (see: Daniel 4:17, 32). All people should worship God the creator (see: Romans 1:20-25). Jesus also will judge the world (see: Acts 17:31; Romans 2:16; Revelation 20:11-15).
Many false gods exist. Some false gods are idols made by man (see: Jeremiah 10:2-10). Satan is called the god of this world (see: 2 Corinthians 4:4). All false gods will perish (see: Jeremiah 10:11).
