What does the Bible say about who will inherit the kingdom of God?

According to 1 Corinthians 6:9-10, the unrighteous, including fornicators, idolaters, adulterers, and others, shall not inherit the kingdom of God. This stark warning serves to remind believers of God's holiness and the seriousness of sin. It emphasizes that those who live in such manner, apart from repentance and faith in Christ, are excluded from salvation. The significance of understanding this truth lies in recognizing the gravity of our sinfulness and the need for a Savior who can cleanse us from our unrighteousness.
