O sing unto the Lord a new song
An excellent one unto the Lord Christ, on account of the great work of redemption and salvation wrought out by him; and because of the new and living way opened by him, and because of the new dispensation of the Gospel, which takes place through him, and for the reasons next mentioned; (See Gill on Psalms 96:1),
for he hath done marvellous things;
by assuming human nature, in that he, being God, became man, took flesh of a virgin, even pure and uncorrupted, a clean thing out of an unclean; which he took into personal union with himself, and that for the sake of sinful creatures: a most marvellous affair this! which calls for a new song from men, as it had from the angels. In this nature he taught wonderful doctrines, at which his hearers were astonished, wondering from whence he had his wisdom; and in it he did many miraculous works, which filled them with amazement above measure; and especially in it he performed the amazing and surprising work of man's redemption, an instance of the marvellous lovingkindness and astonishing wisdom of God; performed in a manner quite stupendous, through Christ's being made under the law both the precept and penalty of it; through his being made sin and a curse for men, even for the ungodly, sinners and enemies; a redemption which is of the souls of men from sin, Satan, and the law; a complete and plenteous one, which includes and secures all the blessings of grace and glory, justification, pardon, adoption, and eternal life. To which may be added the resurrection of himself from the dead, his ascension to heaven, the effusion of the extraordinary gifts of the Spirit on the apostles, the wonderful success of the Gospel in the Gentile world, the support of his interest against all the powers on earth, the destruction of the man of sin, the calling of the Jews, and the bringing in of the fulness of the Gentiles in the latter day; all which marvellous events require a new song of praise: another reason of which follows:
his right hand and his holy arm hath gotten him the victory:
over sin, Satan, the world, death, and hell, in which he has made his people sharers, yea, more than conquerors; and therefore may well sing the new triumphant song to him: the words may be rendered, "hath brought salvation to him" F2; as in ( Isaiah 59:16 ) ( 63:5 ) ; to him personally, he raising himself from the dead, as a triumphant Conqueror; to him mystically, his body the church, to whom he is the author of salvation; or to him, that is, to his Father, in obedience to whose will he wrought out salvation for his people, and for the honour of his name, and for the glorifying of his perfections. This was done by him alone, by his right hand of power, by the mighty arm of his strength, and which no mere creature could ever have performed: and this he did in a way of holiness; his holy arm did it in a way that maintains and secures the glory of divine holiness and justice.
