GODS CAN CHANGE
The Christian God once was deaf to prayers not delivered in Latin. Christians revolted, and the Christian God now understands prayers delivered in all languages.
The Arabic God only understands prayers delivered in Arabic. If the Arabic God could understand all languages, imagine the explosion in Islam.
The above also applies to the Buddhist God that only understands chanting. If everyone could sing, the whole world would be Buddhist.
Fortunately, some Gods are very stubborn and shall never change their ways.
