The Bible says in Genesis that God made human beings in his "image".
This means that Christians believe human beings were made with certain attributes that they share with God. Attributes such as intelligence, creativity, an appreciation of beauty, and sharing a similar set of cardinal moral and spiritual values around love, justice, mercy, etc.
This linked article explains it from a Christian perspective more fully.http://www.relevantmagazine.com/god/deeper-walk/features/23549-qmade-in-the-image-of-godq
AND YET....we find in the Old Testament that God performs or endorses the most morally repugnant acts, such as ethnic cleansing, killing infants and children, causing famines and plagues, drowning the entire human population except eight persons, etc, etc - all actions that any reasonable and objectively sane person naturally finds morally incomprehensible, disgusting, evil.
This article here outlines some of the actions described in the OT that any normal, sane person would naturally find morally abhorrent:http://www.infidels.org/library/modern/raymond_bradley/moral.html
This is really an insurmountable argument against belief in a God as described in the OT, and that the Bible is most definitely not inerrant. There is no surer way of being certain that the descriptions of a God called YHWH and his actions as narrated in the Old Testament are nothing but fiction.
Such ancient written accounts are nothing but the self-serving inventions of Israelites priests to frighten the populace into subservience and submission, in the same way that churches and evangelists today preach scare-mongering nonsense that you will be tormented forever in a hot fiery hell if you don't repent. They should all one and the same be rejected for what they are: morally disgusting lies.
