The link between the Old Testament and the New Testament is the genealogy of the king.
The Old Testament shows that Jesus came to be the king and the New Testament tells us the king is born and get the kingship.
The opposition of the existing forces against the new king was severe. The king of the small land of Juda slaughtered all under two, and the ruler of the empire examine, “Are you the king?” He said, “I am the king, as you have said, born and came for this purpose (John 18:37) The king of the earth, the devil, said, “All these powers and glory have been delivered to me so I can make a deal.”(Luke 4: 6)
Jesus fulfilled his mission and proclaimed that he had secured all the powers of heaven and earth, the kingship.
Therefore, I should instruct all nations to learn and keep all His commands as disciples. (Mt 28: 18-20) I must first teach the conflict with the existing forces. They must know that Jesus is the king and learn the law which is the basis of the governing ideology in His kingdom. He must come and direct rule with us, and we should trade pounds till He comes. (Luke 19: 12,17).
Even though he has all authority, he is ‘the king of the kings’ who will make a nation as a voluntary obedient people. I want to obey his will and obey with love.
