5 Lo, I will send you the prophet Elijah before the great and terrible day of the Lord comes. 6 He will turn the hearts of parents to their children and the hearts of children to their parents, so that I will not come and strike the land with a curse.
Matthew Henry's Commentary on Malachi 4:5-6
Commentary on Malachi 4:4-6
(Read Malachi 4:4-6)
Here is a solemn conclusion, not only of this prophecy, but of the Old Testament. Conscience bids us remember the law. Though we have not prophets, yet, as long as we have Bibles, we may keep up our communion with God. Let others boast in their proud reasoning, and call it enlightening, but let us keep near to that sacred word, through which this Sun of Righteousness shines upon the souls of his people. They must keep up a believing expectation of the gospel of Christ, and must look for the beginning of it. John the Baptist preached repentance and reformation, as Elijah had done. The turning of souls to God and their duty, is the best preparation of them for the great and dreadful day of the Lord. John shall preach a doctrine that shall reach men's hearts, and work a change in them. Thus he shall prepare the way for the kingdom of heaven. The Jewish nation, by wickedness, laid themselves open to the curse. God was ready to bring ruin upon them; but he will once more try whether they will repent and return; therefore he sent John the Baptist to preach repentance to them. Let the believer wait with patience for his release, and cheerfully expect the great day, when Christ shall come the second time to complete our salvation. But those must expect to be smitten with a sword, with a curse, who turn not to Him that smites them with a rod. None can expect to escape the curse of God's broken law, nor to enjoy the happiness of his chosen and redeemed people, unless their hearts are turned from sin and the world, to Christ and holiness. The grace of our Lord Jesus Christ be with us all. Amen.
