Matthew 10:32
"Therefore whoever confesses Me before men, him I will also confess before My Father who is in heaven."
Romans 10:8-10
But what does it say? "The word is near you, even 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 to righteousness, and with the mouth confession is made to salvation.
