Romans 10:8-13 NKJV
But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith which we preach):
 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.
 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.
 For the Scripture says, “Whoever believes on Him will not be put to shame.”
 For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him.  For “whoever calls on the name of the LORD shall be saved.”
Romans 4:3, 7-8 NKJV
For what does the Scripture say? “Abraham believed God, and it was accounted to him for righteousness.”  “Blessed are those whose lawless deeds are forgiven, And whose sins are covered;  Blessed is the man to whom the LORD shall not impute sin.”
