If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For it is by believing in your heart that you are made right with God, and it is by confessing with your mouth that you are saved.

Romans 10:9, 10 NLT

For even the Son of Man came not to be served but to serve others and to give his life as a ransom for many.

Matthew 20:28 NLT
