'Heart' in the Bible

And as you have made your souls clean, being ruled by what is true, and loving one another without deceit, see that your love is warm and from the heart:

My loved ones, I make this request with all my heart, that, as those for whom this world is a strange country, you will keep yourselves from the desires of the flesh which make war against the soul;

But let them be those of the unseen man of the heart, the ever-shining ornament of a gentle and quiet spirit, which is of great price in the eyes of God.

And let him be turned from evil and do good; searching for peace and going after it with all his heart.

Keep open house for all with a glad heart;
