Romans 10:10

For with the heart man believeth, etc. - And be sincere in this: for with the heart, duly affected with a sense of guilt, and of the sufficiency of the sacrifice which Christ has offered, man believeth unto righteousness, believeth to receive justification; for this is the proper meaning of the term here, and in many other parts of this epistle; and with the mouth confession is made unto salvation. He who believes aright in Christ Jesus will receive such a full conviction of the truth, and such an evidence of his redemption, that his mouth will boldly confess his obligation to his Redeemer, and the blessed persuasion he has of the remission of all his sins through the blood of the cross. One grand object of the apostle is to show the simplicity of the Gospel scheme of salvation; and at the same time, its great efficacy, it is simple, and very unlike the law, which was full of rites, ordinances, ceremonies, etc., each of which required to be perfectly fulfilled: and yet, after all, even those who had the utmost zeal for God, and, as conscientiously as possible, observed all the precepts of the law, had not attained to justification nor peace of conscience. Whereas both Jews and Gentiles, who had believed on the Lord Jesus according to the simple declarations of the Gospel, were freely justified from all things from which they could not be justified by the law of Moses: and they had the witness in themselves that they were passed from death to life.

For with the heart - Not with the understanding merely, but with such a faith as shall be sincere, and shall influence the life. There can be no other genuine faith than what influences the whole mind.

Believeth unto righteousness - Believes so that justification is obtained. (Stuart.) In God's plan of justifying people, this is the way by which we may be declared just or righteous in his sight. The moment a sinner believes, therefore, he is justified; his sins are pardoned; and he is introduced into the favor of God. No man can be justified without this; for this is God's plan, and he will not depart from it.

With the mouth confession is made ... - That is, confession or profession is so made as to obtain salvation. He who in all appropriate ways professes his attachment to Christ shall be saved. This profession is to be made in all the proper ways of religious duty; by an avowal of our sentiments; by declaring on all proper occasions our belief of the truth; and by an unwavering adherence to them in all persecutions, oppositions, and trials. He who declares his belief makes a profession. He who associates with Christian people does it. He who acts with them in the prayer meeting, in the sanctuary, and in deeds of benevolence, does it. He who is baptized, and commemorates the death of the Lord Jesus, does it. And he who leads an humble, prayerful, spiritual life, does it. He shows his regard to the precepts and example of Christ Jesus; his regard for them more than for the pride, and pomp, and allurements of the world. All these are included in a profession of religion. In whatever way we can manifest attachment to it, it must be done. The reason why this is made so important is, that there can be no true attachment to Christ which will not manifest itself in the life. A city that is set on a hill cannot be hid. It is impossible that there should be true belief in the heart of man, unless it should show itself in the life and conversation. This is the only test of its existence and its power; and hence it is made so important in the business of religion. And we may here learn,

(1) That a profession of religion is, by Paul, made as really indispensable to salvation as believing. According to him it is connected with salvation as really as faith is with justification; and this accords with all the declarations of the Lord Jesus; Matthew 10:32; Matthew 25:34-46; Luke 12:8.

(2) there can be no religion where there is not a willingness to confess the Lord Jesus. There is no true repentance where we are not willing to confess our faults. There is no true attachment to a father or mother or friend, unless we are willing on all proper occasions to avow it. And so there can be no true religion where there is too much pride, or vanity, or love of the world, or fear of shame to confess it.

(3) those who never profess any religion have none: and they are not safe. To deny God the Saviour before people is not safe. They who do not profess religion, profess the opposite. The real feelings of the heart will be expressed in the life. And they who profess by their lives that they have no regard for God and Christ, for heaven and glory, must expect to be met in the last day, as those who deny the Lord that bought them, and who bring upon themselves quick destruction; 2 Peter 1:2.

10:10 For with the heart - Not the understanding only.Man believeth to righteousness - So as to obtain justification.And with the mouth confession is made - So as to obtain final salvation. Confession here implies the whole of outward, as believing does the root of all inward, religion.
