[bkaycee]

So, if we all try hard enough, avoid sin, do good works, we can go to heaven?

If you avoid sin as you do your good works, yes. Good luck.

So, Jesus died for nothing, if we can make it with Good works?

Who, says we dont perform good works? We were saved to preach the Gospel and to perform good works.

Without the grace of Jesus, which alone saves, you would not have good works.
