If you shall confess with your mouth the Lord Jesus, and shall believe in your heart that God has raised Him from the dead, you shall be saved. For with the heart man believes unto righteousness; and with the mouth confession is made unto salvation."
(Rom. 10:9-10).

“For by Grace are you saved through faith; and that not of yourselves; it is a gift of God;
not of works lest any man should boast."
(Eph. 2:8-9)
