(9) If thou shalt confess with thy mouth.--Interesting as containing the earliest formal confession of faith; that in Acts 8:37 (see Note there) is not genuine.

There is no opposition between the outward confession and the inward act of faith. The one is regarded as the necessary consequence and expression of the other. In the next verse this takes the form of Hebrew parallelism, in which the balanced clauses are regarded as equivalent to each other.

The Lord Jesus.--Jesus as Lord.

Hath raised him from the dead.--Comp. Romans 4:25. Though the death of Christ apprehended by faith is more especially the cause of the Christian's salvation, still the Apostle regards the Resurrection as the cardinal point; for without the Resurrection the proof of the Messiahship of Jesus would have been incomplete, and His death would not have had its saving efficacy.

10:5-11 The self-condemned sinner need not perplex himself how this righteousness may be found. When we speak of looking upon Christ, and receiving, and feeding upon him, it is not Christ in heaven, nor Christ in the deep, that we mean; but Christ in the promise, Christ offered in the word. Justification by faith in Christ is a plain doctrine. It is brought before the mind and heart of every one, thus leaving him without excuse for unbelief. If a man confessed faith in Jesus, as the Lord and Saviour of lost sinners, and really believed in his heart that God had raised him from the dead, thus showing that he had accepted the atonement, he should be saved by the righteousness of Christ, imputed to him through faith. But no faith is justifying which is not powerful in sanctifying the heart, and regulating all its affections by the love of Christ. We must devote and give up to God our souls and our bodies: our souls in believing with the heart, and our bodies in confessing with the mouth. The believer shall never have cause to repent his confident trust in the Lord Jesus. Of such faith no sinner shall be ashamed before God; and he ought to glory in it before men.That if thou shalt confess with thy mouth the Lord Jesus,.... That is, if a man shall make a good, sincere, and hearty confession to God, before the church and people of God, and before the world, that Christ is his Lord and Saviour, whom he desires to serve, and to be saved by; and this as arising from a comfortable experience of the grace of God in his soul, and from a true faith in Christ in his heart, wherefore it follows,

and shall believe in thine heart, that God hath raised him from the dead, thou shalt be saved; for this article of Christ's resurrection includes the several other articles of faith: it supposes his death, and that supposes his life, and the obedience of it; and his life implies his being here on earth, and that his coming down from heaven to do the will of his Father; and this is the rather mentioned, which is here ascribed to God the Father, though not to the exclusion of the Son and Spirit, because that Christ is risen again for our justification, with which true faith is principally concerned; for such a faith is intended, not which lies in a mere assent to the truth of this, or any other article of the Christian religion; but which is concerned with Christ for righteousness, life, and glory; and with such a faith salvation is certainly and inseparably connected.
