So Christ did it all but just in case He didn’t?

[TexasFreeper2009]

I don't exactly see what the issue is here

If someone is saved and salvation alone is all that is necessary - they go to heaven

If someone is saved and does good works, and salvation alone is all that is necessary - they go to heaven

BUT

If someone is saved but doesn't do good works, and salvation alone isn't enough they risk going to hell.

...

I see no downside to doing good works in addition to being saved.

You can't argue that salvation alone is enough, but then say that doing good works after being saved could jeopardize your salvation. If no sins you commit after being saved can make you lose your salvation then how could doing good works jeopardize it? that makes no sense.

Just out of curiosity, how do you respond to Collossians 1:24:

Now I rejoice in my sufferings for your sake, and in my flesh I do my share on behalf of His body, which is the church, in filling up what is lacking in Christ's afflictions. - New American Standard Version (1995)
