It is in your own mouth and heart. It is “this good news of the kingdom.” (Matthew 24:14) As Christ’s apostle said: “If you publicly declare that ‘word in your own mouth,’ that Jesus is Lord, and exercise faith in your heart that God raised him up from the dead, you will be saved. For with the heart one exercises faith for righteousness, but with the mouth one makes public declaration for salvation.”​—Romans 10:5-10.

For the word is very near you, in your own mouth and in your own heart, that you may do it.”​—Deuteronomy 30:11-14.
