Romans 1:9 states "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." According to this scripture, if one simply proof texted it -- meaning they took it out of context and focused one that one single verse on which to base doctrine--one could say that all we had to do to be saved would be to declare that Jesus is the Christ and that He was resurrected. As important as that is, it is certainly not enough to save us.
In Greek, the word "confess" would more accurately be defined as "covenant" or "connect. So although it's important to confess that Jesus is the Christ and believe on Him and His Atonement, salvation comes from connecting ourselves to Him. When we live our lives in harmony with His life and teachings, we become more like Him and therefore will be worthy to receive salvation.We must do more than confess; our lives should be a greater example of our conversion to the Lord than our words.
