Is the God of the Old Testament the same as the God of the New Testament? (Lk 15: 1-32) (24 OT)

The Gospel today shows us a God who seeks us out, to bring us back to Himself, and His Love. However we often hear that the God of the Old Testament is Angry and seeks to destroy His people. This homily looks at both the Old Testament Reading where God seeks to destroy His people after the worship the Golden Calf, and at today's Gospel showing how radical and far reaching God's Love is,  and shows it is the same God; who is forever unchanging and Merciful.
