Is God's kingdom and Heaven the same?

The kingdom of God is mentioned in the Old Testament and New Testament as a place inhabited by the Triune God, the Church, angels, and creatures. (Genesis, Psalms, Revelation 12, 15, 17, 19). According to the Apostle Paul, immoral and corrupt being will not inherit the Kingdom of Heaven (1Corinthians 6:9-10). Humans of flesh and blood will not spend eternity in the Kingdom of God (1Corinthians 15:50). Humans' mortal bodies will be transformed into immortal beings (1Corinthians 15:52-54). The Kingdom is often referred to as Heaven in conversations with non-Christians . What is your opinion?
