We define God to be capable of doing everything.Why cannot almighty convince every human being about its existence by exercising it's divine powers and change the mentality of all atheists to that of theists ,as it's motive in the existence seems to bring all under theist thought. Why a human has to interfere in making a human believe in God and abide by God's rules. And why does not God becomes visible if there are so many atheists are still existing in the world.
