Christians, why do you see your god as "loving"?

The command to worship one God in one way only, to the exclusion of all others, seems originally to have been a reflection of uniting a people within their social structure and engendering enmity against other peoples who might compete for, or already possess, desired land and resources, and ‘justification’ for their genocide related in several places in the Bible such as Numbers 31:17-18 "Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him. But all the women children, that have not known a man by lying with him, keep alive for yourselves".
