During the time of Jesus, the scribes were Jewish scholars and teachers of law they didn’t believed that Jesus was both human and divine. To them Jesus was only human and as they claim the human Jesus is the Son of David or descendant of King David.
But David inspired by the Holy Spirit called Him Lord, Jesus was indirectly telling the Jews that if David called Him Lord. Then they should also believe in Him as the Son of God not as a son of David.
Unlike the Jews, we believe that Jesus is the Son of God; He became human and died on the cross because of Jesus’ love for us.
How do we respond to His love?
There are also those who are not fully aware of Jesus’ humanity and divinity: we are therefore being challenged by the gospel to spread the good news about our Lord Jesus.
