Romans 10:9 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.
How marvelous and sure is this statement:"… thou shalt be saved"! One could perhaps translate this a little differently as,"… thou shalt receive (have) salvation!" Upon such confession and believing one is no longer lost but has been saved and granted eternal life.
Romans 10:10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
This verse again set forth the two necessary things to be done by man in an affirmative way:
(1) confession with the mouth that Jesus is lord, and
(2) believing with the heart that God did raise Jesus Christ from the dead. The one brings with it the necessary justification and granting of righteousness before God, the other assures of the necessary salvation.
