'Hearts' in the Bible

who also sealed us and gave us the Spirit in our hearts as a down payment.

You yourselves are our letter, written on our hearts, known and read by everyone,

revealing that you are a letter of Christ, delivered by us, written not with ink but by the Spirit of the living God, not on stone tablets but on tablets of human hearts.

For God, who said "Let light shine out of darkness," is the one who shined in our hearts to give us the light of the glorious knowledge of God in the face of Christ.

Now as a fair exchange -- I speak as to my children -- open wide your hearts to us also.

Make room for us in your hearts; we have wronged no one, we have ruined no one, we have exploited no one.

I do not say this to condemn you, for I told you before that you are in our hearts so that we die together and live together with you.
