Charles Spurgeon Commentary Romans 10:8-10

"But what saith it? The word is nigh thee, in thy mouth, and in thy heart: that is, the word of faith, which we preach: because if thou shalt confess with thy mouth Jesus [as] Lord, and shalt believe in thy heart that God raised him from the dead, thou shalt be saved: for with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation." — Romans 10:8-10 (ASV)

Even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.

To trust the risen Saviour, to put your soul into his hands, and then to confess your faith by publicly declaring that you are on his side—these are the things which he demands of us in order to our salvation, and these he enables us to render. Are there any believers here who have never confessed Christ? Let them question themselves how far they can be said to be true disciples of him who demands that, where there is faith, confession of it should be made.

If you believe in Jesus, look at this Scripture, and feel ashamed of yourself if you have been ashamed to own him as your Saviour; for is not the promise this—that, if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved?
