Q: How are we to understand God's actions in the Old Testament, when He ordered so many killings and other things we now consider immoral, while Jesus in the New Testament reveals a loving Father?
In the Old Testament, God permits the people of Israel to put the population inhabiting the Promised Land under the ban, killing every person who inhabited the land. Contrast this to Christ in the New Testament, who teaches to love one's enemies and to turn the other cheek. What a contrast for the same God!
