The kingdom of God is referenced often in the gospels (e.g., Mark 1:15; 10:15; 15:43; Luke 17:20) and other places in the New Testament (e.g., Acts 28:31; Romans 14:17; 1 Corinthians 15:50). The kingdom of God is synonymous with the kingdom of heaven. However, the kingdom of heaven is only used in the Gospel of Matthew. The concept of the kingdom of God takes on various shades of meaning in different passages of Scripture.
