That’s the rub isn’t it.
There are a lot more people walking around, steeling, cheating on their wives, talking bad about everyone they know thinking they’re all good because they “believe in Jesus”.
Let’s say hypothetically that baptism is the only law of G-d and he says it should be done every week there will be people thinking that earns their salvation. I know people who believe that now. (My kids went to a COC school). There are people that say “I believe in Jesus but I’m not doing that. It’s not worth the effort or I just don’t want too. I know those people too. Both think they’re saved pointing at the others saying that guy doesn’t get it.
But it’s clear from the rest of scripture that G-d is concerned about your heart (he is) psalms 119 is a pitcher of what G-d wants. In our hypothetical, G-d doesn’t actually care (in terms of salvation) if you do your baptism or not. He wants you to want too. That should be a test for everyone who calls themselves believers. Do you want to please G-d? Do you want to be baptized? If you don’t want to then you might as well not do it because it’s of no value to you.
You know there’s always scripture for my beliefs.
Isiah 64
For from days of old they have not heard or perceived by ear,
Nor has the eye seen a God besides You,
Who acts in behalf of one who waits for Him.
5 You meet him who rejoices in doing righteousness,
Who remembers You in Your ways.
Behold, You were angry, for we sinned,
We continued in [
c]our sins for a long time;
Yet shall we be saved?
6 For all of us have become like one who is unclean,
And all our righteous deeds are like a filthy garment;
And all of us wither like a leaf,
And our wrongdoings, like the wind, take us away.
Isiah says all your good deeds don’t save you.
