Even so then at this present time also,.... In which the apostle lived, the time of preaching the Gospel, the accepted time, the day of salvation, which then was, and also now is; at that time when the Gospel was sent unto the Gentiles, and God took out of them a people for his name; when multitudes of them were converted, and embraced the faith of Christ; and when the Jews in general had rejected the Messiah, killed the Lord Jesus, persecuted his apostles, and contradicted and blasphemed the Gospel; yet still God had made a reserve of some among them, for himself:there is a remnant; alluding either to Isa 10:21, or to the oracle delivered to Elijah, saying, "I have reserved", or "left", &c.
1Ki 19:18, that as God had reserved for himself, in Elijah's time, a number of persons, who had not gone into the idolatrous worship of Baal, when the greater part of the Israelites did, so he had taken care to make a like reserve in the apostle's time, when the bulk of the Jewish nation had refused the Messiah, and despised his Gospel.
This is a further proof, that God had not cast away all the people of the Jews; and that as Elijah was not the only worshipper of the true God in his time, so the apostle was not the only instance of grace among that people now; there was a number of them; the number of the disciples after our Lord's ascension, was an hundred and twenty; upon the first sermon preached by Peter, three thousand were converted, and added to them; after that, they are said to be about five thousand, and still multitudes were added, both of men and women, and a great company of the priests were obedient to the faith; so that before the dispersion of the church at Jerusalem by a persecution, there might be at least such a number called by grace, as God had reserved in Elijah's time; though these, when compared with the generality of the nation, which remained in unbelief, were but a few, and therefore called a "remnant", or a "reserve", as the word may be rendered; for these were a set of men, whom God had reserved and preserved in his Son, and in the covenant of his grace, from everlasting; and had kept a watchful eye over them in time, reserved them in his providence, and saved them to be called; and by calling them, had reserved them by his grace, and preserved them by his power, from the general unbelief, impenitence, blindness, and ignorance, which prevailed over the people of the Jews; which reserve was not owing to their superior goodness, they being in no wise, with respect to nature, birth, and privileges, better than those who were not reserved; nor to the disposition of their minds and wills, their minds and consciences being defiled, and their wills naturally as obstinate and perverse as others; nor to any good works done by them, since works before calling are not properly good, and those after are the fruits of that grace: but this reverse was made,according to the election of grace; God's choice of these persons before the world was, which is the source and spring of all the blessings of grace, both in time eternity: hence these persons were put into the hands of Christ, secured in an everlasting covenant, took special care of by divine Providence, were called by grace, justified, sanctified, and at last glorified: and this choice is owing to grace, for not men's choice of God's grace, but God's choice, owing to his, own grace, is here meant.
