Romans 10:8

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)...

Matthew 7:24-27

Therefore whoever hears these sayings of Mine and does them, I will liken him to a wise man who built his house on the rock. And the rain descended, the floods came, and the winds blew and beat on that house, and it did not fall, for it was founded on the rock. Now everyone who hears these sayings of Mine and does not do them will be like a foolish man who bult his house on the sand. And the rain descended, the floods came, and the winds blew and beat on that house, and it fell. And great was its fall.
