Christians who become wicked and sinful will be severely punished for their sins in this life, and may also lose their rewards in Heaven. However once someone accepts Jesus as their saviour, they are saved forever. Salvation is only by faith i.e. BELIEVING, and once saved, always saved. John 10:28 “And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand." Acts 16:30-31 30And brought them out, and said, Sirs, what must I do to be saved? 31And they said, **Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house**. Salvation is a free gift that can never be taken away. https://rumble.com/v33k2vm-the-bible-way-to-heaven.-pastor-jason-robinson.html ^^ if you want to hear the Gospel of how to be saved. Ephesians 2:8-9 8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast.
