4. With what view he shall be sent on this errand: Lest I come and smite the earth, that is, the land of Israel, the body of the Jewish nation (that were of the earth earthy), with a curse. They by their impiety and impenitence in it had laid themselves open to the curse of God, which is a separation to all evil. God was ready to smite them with that curse, to bring utter ruin upon them, to strike home, to strike dead, with the curse; but he will yet once more try them, whether they will repent and return, and so prevent it; and therefore he sends John Baptist to preach repentance to them, that their conversion might prevent their confusion; so unwilling is God that any should perish, so willing to have his anger turned away. Had they universally repented and reformed, their repentance would have had this desired effect; but, they generally rejecting the counsel of God in John's baptism, it proved against themselves (Luke vii. 30) and their land was smitten with the curse which both it and they lie under to this day. Note, Those must expect to be smitten with a sword, with a curse, who turn not to him that smites them with a rod, with a cross, Isa. ix. 13. Now the axe is laid to the root of the tree, says John Baptist, and it is ready to be smitten, to be cut down, with a curse; therefore bring forth fruit meet for repentance. Some observe that the last word of the Old Testament is a curse, which threatens the earth (Zech. v. 3), our desert of which we must be made sensible of, that we may bid Christ welcome, who comes with a blessing; and it is with a blessing, with the choicest of blessings, that the New Testament ends, and with it let us arm ourselves, or rather let God arm us, against this curse. The grace of our Lord Jesus Christ be with us all. Amen.
