Christians like the Old Testament stories that have mercy and inspiration in them, but some Christians find the stories of wrath and destruction to be offensive.For example, Samuel instructs King Saul to completely destroy the Amalekites.
“Now go and smite Amalek and utterly destroy all that they have; do not spare them, but kill both man and woman, infant and suckling, ox and sheep, camel and ass” (I Samuel 15:3). Usually what Christians try to do is forget such texts are in the Old Testament, focus on the New Testament and pretend everything is alright.
