1607. That 'for all the land which you see I will give to you' means the heavenly kingdom which was to be the Lord's is clear from the meaning of 'land'- the land of Canaan in this context since the words used are 'the land which you see'- as the heavenly kingdom. Indeed the land of Canaan represented the Lord's kingdom in the heavens, which is heaven, and also the Lord's kingdom on earth, which is the Church. This meaning of 'land' has been discussed frequently already. That the kingdom in heaven and on earth was given to the Lord is clear from various places in the Word, as in Isaiah,
A Boy is born, a Son is given to us; and the government will be upon His shoulder, and His name will be called, Wonderful, Counsellor, God, Hero, Father of Eternity, Prince of Peace. Isa 9:6.
I saw in the night visions, and behold with the clouds of the heavens One like the Son of Man was coming, and He came even to the Ancient of Days, and they brought Him near before Him. And to Him was given dominion and glory and kingdom, and all peoples, nations, and languages will serve Him. His dominion is an eternal dominion which will not pass away, and His kingdom one that will not perish. Dan 7:13, 14.
The Lord Himself also says the same: in Matthew,
All things have been delivered to Me by My Father. Matt 11:27; Luke 10:22.
Elsewhere in Matthew,
[All] power in heaven and on earth has been given to Me. Matt 28:18.
You have given to the Son power over all flesh in order that all You have given Him, to them He may give eternal life. John 17:2, 3.
And 'sitting on the right hand' has the same meaning, as in Luke,
From now on the Son of Man will be seated at the right hand of the power of God. Luke 22:69.
 As regards all power in heaven and on earth being given to the Son of Man, it should be recognized that the Lord already had power over all things in heaven and on earth before He came into the world, for He was God from eternity and He was Jehovah, as He Himself plainly declares in John,
Now, Father, glorify Me in Your Own Self with the glory I had with You before the world was. John 17:5.
And in the same gospel,
Truly, Truly, I say to you, before Abraham was, I am.a John 8:58.
In fact He was Jehovah and God to the Most Ancient Church which existed before the Flood, and was seen by them. He was also Jehovah and God to the Ancient Church which existed after the Flood; and He was the One whom all the religious observances of the Jewish Church represented, and the One they worshipped. The reason the Lord says that all power in heaven and on earth has been given to Him, as though it had not been His till then, is that 'the Son of Man' is used to mean His Human Essence which became Jehovah as well after it had been united to His Divine Essence. Power was given to Him at that point, which would not have been possible until He was glorified, that is, until His Human Essence as well, through union with the Divine Essence, had life in Itself and likewise became Divine and Jehovah, as He Himself declares in John,
As the Father has life in Himself, so He has granted the Son to have life in Himself. John 5:26.
 It is His Human Essence or External Man that is named 'the Son of Man' in the passage quoted from Daniel, and 'a Boy born, a Son given to us' in the passage quoted from Isaiah. The fact that the heavenly kingdom would be given to Him, and all power in heaven and on earth, was shown and promised to Him then, and is the meaning of the statement 'all the land which you see I will give to you, and to your seed after you for ever'. This was before His Human Essence had been united to His Divine Essence, a union which took place when He had overcome the devil and hell, that is to say, when by His own strength and powers He had cast out all evil, which alone causes the severance.
