If you've been in Hell, will you have a chance to accept Christ when the final judgment takes place?
The clear emphasis in Scriptures is that our only opportunity for salvation is in this life. There will be no second chances.
Hebrews 9:27 is one example: “And just as it is appointed for man to die once, and after that comes judgment...” Judgment follows death, and hell (hades) is part of that judgment. Later on, the Great White Throne of judgment and the lake of fire in Revelation 20 is the final part of that judgment.
