⁸ But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
⁹ 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.
¹⁰ For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
¹¹ For the scripture saith, Whosoever believeth on him shall not be ashamed.

Our FAITH must be strong enough to lead us to CONFESS. We publicly CONFESS our FAITH (not our sins) to be saved.

Look next at an actual example of this in the New Testament.
