if the concept of god is ever loving,just and merciful,then it is impossible to exist, because being loving,merciful and just at the same time contradicts itself, if he is only ever loving he is then not a free being and is therfore a robot and all its expression is artificial! if he is all the above plus omnipotent,omniscient,omnipresent, that god is impossible to exist because all these attributes can't exist alongside eachother and therefore renders him as unrealistic and impossible as a square circle or a loving rock!
