"If he loved God’s law then so should we."

Michael Kruger on "So, What Did Jesus Think about the Old Testament?":

.... If Jesus is who he claims to be, then surely his opinion should be very influential in shaping our own.... Should we bail on the Old Testament?

Not at all. Here are three things that Jesus believed about the Old Testament:

1. The Old Testament was historical. Generally speaking, Jesus viewed the Old Testament as telling about people that really existed and events that really happened. Sure, there are poetic portions (e.g., the Psalms) and apocalyptic portions which are highly symbolic (e.g., Ezekiel), but Jesus understood the historical portions to be, well, historical. ....
2. The Old Testament was authoritative. In all of Jesus’ disputes and debates (and there were many), the highest court of appeal was always what Scripture had to say. Curiously, this was even an agreed-upon reality with Jesus’ enemies. Despite all their theological disagreements, they never disagreed about the role of Scripture as the ultimate authority. ....
3. The Old Testament was inspired. On top of this, Jesus affirmed most plainly that the Old Testament contains the words of God himself. When it speaks, God speaks. Take, for example, Matt 19:4: “Have you not read that he who created them from the beginning made them male and female, and said, “Therefore a man shall leave his father and mother…” (more, elaborating on each point)
