'Hearts' in the Bible

Because they are united in love, I pray that their hearts may be encouraged by all the riches that come from a complete understanding of the full knowledge of the Messiah, who is the mystery of God.

Let the peace of the Messiah also rule in your hearts, to which you were called in one body, and be thankful.

Let the word of the Messiah inhabit you richly with wisdom, teaching and admonishing one another with psalms, hymns, and spiritual songs, and singing to God with thankfulness in your hearts.

I am sending him to you for this very reason, so that you may know how we are doing and that he may encourage your hearts.
