¹⁰For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. ¹¹As Scripture says, “Anyone who believes in him will never be put to shame.” Romans 10:10-11

That is the clearest statement in the Word of God on how to be saved. Paul makes it very simple. He says that it begins with the confession of the mouth: Jesus is Lord. He means that the mouth is the symbol of the conscious acknowledgment to us of what we believe. It means that we have come to the place where we recognize that Jesus has the right to lordship in our lives. Prior to this point we have been lord of our lives, and we have run our own affairs. But there comes a time, as God's Spirit works in us, that we see the reality of life as God has made it to be, and we realize Jesus is Lord.
