philosophically, the reality of evil challenges claims that god is omnibenevolent, but christians nevertheless trust in god's love from their own experience and on the basis of biblical teaching
the Old Testament uses the Hebrew term hesed, often translated as 'steadfastlove', to depict god's dependable commitment to the covenant with Israel
the new testament equivalent of hesed is the greek word agape, which denotes god's selfless, self-giving, generous and unconditionallove for humanity
according to the writer of 1 John, 'god is love'- 1 John 4:8
agape is part of the nature of the trinity
because they are created in god's image, human relationships have agape at their heart
hence Jesus' two greatest commandments: love of god and love of neighbour
