The amazing thing is, when you find true reality, and see the big picture, you can actually fit these Old Testament events into that picture; the picture of God, who is love.
Admittedly, a couple are a squeeze, however they still fit.
Believe it or not.
As a start, you'll need to understand that Jesus is actually the God of the Old Testament as well as the New Testament. Try that on for size...
