4 Bible Verses about Speaking With The Mouth

[Psa. 10:7 says], "Their speech is full of cursing and bitterness."

And after many questions were asked [about it] Peter stood up and addressed the assembly [including the former Pharisees who were now brothers]: "Brothers, you are aware that some time ago God decided that, from among your number, it would be through my ministry that the Gentiles would hear and believe the Gospel message.

But what does the Scripture say [about being made right with God]? [Deut. 30:14 says], "The message of God is near you [i.e., it is not difficult to comprehend]. It is on your lips and in your heart." This is the message of faith [in Christ] which we [apostles] preach.

For a person believes [in Christ] with his heart in order to be made right with God, and he makes a profession with his lips in order to be saved.
