You have a funny definition of 'many'- there's 2 billion Christians in this world, and only 70 million of them think that things such as baptism is a 'work'.
You all ignore the scriptures:
Romans 9:8
This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as offspring
Galatians 3:29
And if you are Christ’s, then you are Abraham’s offspring, heirs according to promise.
No matter what, you all chop and plaster scripture to fit your faulty beliefs- even if the Bible tells you to your face these things, you still want to separate Jew and Gentile according to what God commands.
James even says that 'faith without works is a dead faith'- that isn't a command to the Jews, that's a statement of fact. And even then, you talk the nonsense you talk now, that 'we aren't believers'.
You do need to prove it, because you're theology is idiotic and based in contemptible interpretation.
The fact is that you all simply just don't think baptism is a necessary thing to have in church- you all reject tradition, works, and try to get by on some easy believey faith that you leave sitting on the church bench.
