Omnibenevolence has been defined variously as perfect goodness and as goodness that is extended to and through all things. While Christians typically consider God to be omnibenevolent, the Bible does not explicitly say so. Some Christians infer omnibenevolence from passages of Scripture describing God's perfection. Other Christian philosophers believe that the very concept of moral goodness has no applicability to God. According to that line of reasoning, moral goodness has to do with fulfilling one's duties, of which God, being God, has none. Another way of looking at it is that if moral goodness is based on following God's will, then calling God good is a tautology.
