Of course. Read the thread. I've said as much. However, we are dealing with certain scriptures worded certain ways, and some people obviously believe that God is responsive to the prayers of sinners. You can be on my side of the debate arguing that God is not responsive.
I suppose that really depends on what you mean by "sinners".
The verse in the OP contrasts "sinners" with those that worship God
and do His will.
This means that "sinners" are those that do not worship God and those that do not do His will.
God does not respond to those that do not worship Him.
God does not respond to those that worship Him but do not do His will.
Being omnipresent would make Him capable of hearing everything, literally. Sure.
"omnipresent" is a Hellenistic myth and not fully supported by scripture.
The "omnipresent" nature of God is contradicted by God being fed information from the angels going up and down the "ladder", the seven eyes of god running to and fro through the whole earth, and several other passages of scripture.
