no i said they come together as in a package deal your not going to have grace with out mercy.once again mercy is not getting what we deserve .grace follows after not getting it paul wrote saved by Grace was he merciful to the ones who offered strange fire was it mercy when they was hauling the ark of the covenant on a cart. and hit a chug hole. the 2 if memory serves right touched the ark poof burnt toast so if i am saved by grace i am forgiven the law was our school master until Christ came .the law did nothing more than tell you what sin was . it had no power to save .
I can't go deep enough here to fix your circular reasoning...since you are also confusing holiness and righteousness. God can forgive righteousness issues...but holiness issues demand a swift justice. So then re-read (if you care to) the differences I listed...since you are not understanding any of them that I listed. The errors just compound in this way so that there is no easy way to untangle the ideas. You need to start again with a fresh understanding of what is foundational and build again slowly.
God goes easy on the humble...but He puts the proud through the wringer.
