I think many Christian’s struggle when reading the Old Testament because so much of it is about fighting God and the consequences of such behavior. Adam and Eve fought God and his will and chose to do life on their terms, or at least they thought that’s what they were doing, rebelling against a loving provider. Moses fought God about his will and his calling and Israel was constantly either fighting God, their own countrymen or their neighbors.  I think all this fighting in mankind’s history in the Old Testament persuaded many believers today to only read the New Testament, because Jesus seems to be all about peace and love, or at least it seems that way.
