Adam Clarke's Bible Commentary Verse 8. Ask of me, and I shall give thee ] Here a second branch of Christ's office as saviour of the world is referred to; viz., his mediatorial office. Having died as an atoning sacrifice, and risen again from the dead, he was now to make intercession for mankind; and in virtue and on account of what he had done and suffered, he was, at his request, to have the nations for his inheritance, and the uttermost parts of the earth for his possession.
He was to become supreme Lord in the mediatorial kingdom; in consequence of which he sent his apostles throughout the habitable globe to preach the Gospel to every man.
Matthew Henry Commentary
Verses 7-9 - The kingdom of the Messiah is founded upon an eternal decree of God the Father. This our Lord Jesus often referred to, as what he governe himself by. God hath said unto him, Thou art my Son, and it become each of us to say to him, Thou art my Lord, my Sovereign'. The Son, i asking the heathen for his inheritance, desires their happiness in him so that he pleads for them, ever lives to do so, and is able to save to the uttermost, and he shall have multitudes of willing, loyal subjects among them. Christians are the possession of the Lord Jesus; they ar to him for a name and a praise. God the Father gives them to him, when by his Spirit and grace, he works upon them to submit to the Lor Jesus.
