Romans 10:9 If you confess with your mouth that Jesus is Lord and believe in your heart that God raised hi from the dead, you will be saved.
Pretty straight forward verse about salvation, while we want to keep in context God’s sovereignty established in Chapter 9.  The reality is this is the message we take to all people, that they must confess and believe. On the service it seems easy enough, but the issue remains will the heart submit to God’s mode of salvation. Will you quit looking to your own self-righteousness, will you quit trying to do it on  your own.  This is a matter of faith, can you trust God to save you.  At the heart level salvation is to stop trusting in yourself and trusting in God.
