Chanting God's name would be pretty awkward when I don't worship that god. It's also pretty strange to think about worshipers of that god caring about karma since that's a concept from Eastern religions. I guess there are probably syncretic religions that blend worship of this Western monotheist god with belief in reincarnation and karma? Not part of my traditions, at any rate.
The OP appears to be Sikh, which is both Eastern and monotheistic.
