Sometimes, when comparing the New Testament with the Old Testament, it is said that the God of the Old Testament is about wrath and judgement but the God of the New Testament is one of grace and love.
Personally I find this way too simplistic. Not that I don’t see a significant difference between the revelations of Moses and Jesus. The sacrificial systems of Moses and Jesus were worlds apart after all.
But such statements do, I think, overstate the differences. After all, we know Jesus got angry and warned of judgement, and we know Moses interceded with God to show mercy towards sinful Israel. This was the same God. Even if it wasn’t the same revelation. Jesus went considerably beyond Moses, but he was in the line of Moses.
