It is written in Revelations 20:15 that those whose names are not found recorded in the Book of Life will be hurled into the Lake of Fire.
Is your name recorded in the Book of Life? If you are not sure, seek God. He is willing to forgive you of all your sins no matter what you have done. He is the only One who can purify you from all unrighteousness. You only need to seek Him and ask for His forgiveness. You may do this by sincerely praying this prayer:
Lord Jesus, I have sinned against You. I repent of and permanently turn away from all of my sins. Please forgive me and free me from all evil and wickedness. Loose me from all curses. Cleanse me from all unrighteousness and write my name in The Book of Life. Lord Jesus, I am asking that You dwell in my life forever and seal me with Your Holy Spirit. It is in Your name that I pray this prayer. Amen.
