As the most frequently quoted Psalm in the New Testament, Psalm 110 is very important. It sheds crucial light on the identity of the Messiah, showing that not only is He the descendent of David (David’s son) but also David’s Lord.
Jesus raised this issue with the Pharisees in Matthew 22:41-46:
Matthew 22:41–46 While the Pharisees were gathered together, Jesus asked them, Saying, What think ye of Christ? whose son is he? They say unto him, The Son of David. He saith unto them, How then doth David in spirit call him Lord, saying, The Lord said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool? If David then
callhim Lord, how is he his son? And no man was able to answer him a word, neither durst any man from that day forth ask him any more questions.
The Scriptural proof of this point was so convincing that it silenced all of Jesus adversaries and skeptics. Most did not believe but they could not refute Jesus’ point.
What this teaches us is the ‘son of David’, the Messiah is the Lord God, appointed by Jehovah LORD, who will come to rule and reign over the earth, put down all enemies, and set up a new eternal priesthood, talked about in Hebrews 7-10.
A big part of believing on Jesus is accepting Him as Lord, as God the Son, co-equal, co-eternal with the Father. If He was only a good man, a good teacher, then His death would not be sufficient and His claims would be false. To believe on the Lord Jesus Christ is to accept Him not only as Saviour but also as Lord.
We can rejoice in our Saviour Jesus Christ, knowing that to Him has been promised the kingdom by God. He is coming back with His saints (v.3). He will rule as a King and priest. He will defeat all His enemies, judge the heathen, and be exalted over all (v.4-7).
