My wife prepared delicious supper for my family,

thus

she should take the credit (gong1 lao2) for it,

I should not take any credit for what she did,

likewise

Bible taught us
God should take all credit for each and every person's salvation
because it is a result of God's work,
man should not take any credit for his salvation if he is saved.

this is the real argue concerning salvation,
I am not smart enough to invent this argue,
it has been lasting for a long time,

God version: God did all things to make man be saved,
man version: I am saved because I believed

argument from opposite:
if you are not willing, even God cannot force you to believe,
you can believe because God did something first

it is crystal clear
which one is true
which one is false
