'Kingdom' in the Bible

For the kingdom of God is not in word, but in power.

Do ye not know that unrighteous persons shall not inherit the kingdom of God? Do not err: neither fornicators, nor idolaters, nor adulterers, nor those who make women of themselves, nor who abuse themselves with men,

nor thieves, nor covetous, nor drunkards, nor abusive persons, nor the rapacious, shall inherit the kingdom of God.

Then the end, when he gives up the kingdom to him who is God and Father; when he shall have annulled all rule and all authority and power.

But this I say, brethren, that flesh and blood cannot inherit God's kingdom, nor does corruption inherit incorruptibility.
