a. How then does David in the Spirit call Him “Lord”: The Pharisees were partially right in saying that the Messiah is the Son of David. But they didn’t have a complete understanding of who the Messiah is. He is not only David’s Son (a reference to His humanity), but He is also David’s Lord (a reference to the deity of Jesus, the Messiah).
The Pharisees, among whom was Paul, believed in the Resurrection of the dead.
Acts 23:
6 But when Paul perceived that the one part were Sadducees, and the other Pharisees,
he cried out in the council, Men and brethren, I am a Pharisee, the son of a Pharisee:
of the hope and resurrection of the dead I am called in question.
7 And when he had so said, there arose a dissension between the Pharisees and the
Sadducees: and the multitude was divided.
8 For the Sadducees say that there is no resurrection, neither angel, nor spirit: but
the Pharisees confess both.
9 And there arose a great cry: and the scribes that were of the Pharisees' part arose,
and strove, saying, We find no evil in this man: but if a spirit or an angel hath spoken
to him, let us not fight against God.
Paul attained the deeper Truth
1 Corinthians 15:
20 But now Messiah has been raised from the dead, the firstfruits of those who have
fallen asleep.
21 For since death came through a man, the resurrection of the dead also has come
through a Man.
22 For as in Adam all die, so also
in Messiah will all be made alive.
23 But each in its own order:
Messiah the firstfruits; then, at His coming, those
who belong to Messiah;
24 then the end, when He hands over the kingdom to God the Father
after He has
destroyed all rule and all authority and power.
25 For He must reign until
He has put all His enemies under His feet.
26 The last enemy to be destroyed is death.
27 For God has “put all things in subjection underneath His feet.” But when the psalmist
says that “all” has been put in subjection, it is clear that this does not include God Himself,
who put all things under Messiah.
28 Now when all things become subject to Him, then the Son Himself will also become
subject to the One who put all things under Him,
so that God may be all, in all.
