You don’t need to anything to end up in eternal damnation. The whole world is already judged and condemned because of sin, because all have sinned and they come short of the glory of God. But Jesus Christ can remove the guilt of your sin and give you eternal life IF you repent and ACCEPT Him as your LORD and MASTER and to OBEY and SERVE Him for the rest of your life. Then you become part of His kingdom. If you reject Jesus Christ YOU WILL PERISH.
You need to GO AFTER Him, you need to OBEY Him, you need to SERVE Him as LORD. Jesus said:”Whoever WISHES to come after Me MUST deny himself, pick up his cross every day and come here FOLLOW ME.”
Very few people will be saved. They asked Jesus whether those who are being saved are few and He said to them:”Straight is the gate and narrow is the door that leads to life and FEW there be that find it. Strive HARD to enter the narrow door. You don’t need to do anything to end up in hell but you need to STRIVE HARD, you need to GO AFTER Jesus every day, you need to OBEY Him, you need to LIVE HOLY and RIGHTEOUSLY, you need to live in close relationship with Jesus Christ EVERY DAY if you want eternal life. If you turn away from Him YOU ARE DOOMED, you are LOST!
It is YOUR RESPONSIBILITY to look after YOUR SALVATION. YOU have to work out your salvation with fear and trembling UNTIL the very very end. Your salvation is YOUR RESPONSIBILITY. It depends on YOUR relationship with Jesus, whether YOU follow Him and serve Him as Lord and Master. Jesus Christ will say to many who believed that they were saved:”Go away, I never knew you, you workers of wickedness,” because those people did not follow after Jesus. They did not LISTEN to Him, they did not OBEY HIS WORDS. They were workers of wickedness. You need to follow Jesus EVERY DAY until the very end or else YOU WILL PERISH.
May Jesus bless you.
