Matthew 12:28

But if I cast out devils by the Spirit of God--In Luke (Luk 11:20) it is, "with (or 'by') the finger of God." This latter expression is just a figurative way of representing the power of God, while the former tells us the living Personal Agent was made use of by the Lord Jesus in every exercise of that power. then--"no doubt" (Luk 11:20). the kingdom of God is come unto you--rather "upon you," as the same expression is rendered in Luke (Luk 11:20): --that is, "If this expulsion of Satan is, and can be, by no other than the Spirit of God, then is his Destroyer already in the midst of you, and that kingdom which is destined to supplant his is already rising on its ruins."

In this chapter, we have, I. Christ's clearing of the law of the fourth commandment concerning the sabbath-day, and vindicating it from some superstitious notions advanced by the Jewish teachers; showing that works of necessity and mercy are to be done on that day (Mat 12:1-13). II. The prudence, humility, and self-denial of our Lord Jesus in working his miracles (Mat 12:14-21). III. Christ's answer to the blasphemous cavils and calumnies of the scribes and Pharisees, who imputed his casting out devils to a compact with the devil (v. 22-37). IV. Christ's reply to a tempting demand of the scribes and Pharisees, challenging him to show them a sign from heaven (Mat 12:38-45). V. Christ's judgment about his kindred and relations (Mat 12:46-50).

12:28 The Pharisees were being confronted with and were rejecting the Kingdom of God itself (see Luke 17:20-21; 1 Jn 3:8). Jesus’ miracles brought the power of the Kingdom into the present reality; its ultimate consummation awaits Christ’s second coming.
