'Hearts' in the Bible

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

You are our letter, written in our hearts, known and read by all men;

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

For God, who said, “Light shall shine out of darkness,” is the One who has shone in our hearts to give the Light of the knowledge of the glory of God in the face of Christ.

Make room for us in your hearts; we wronged no one, we corrupted no one, we took advantage of no one.

I do not speak to condemn you, for I have said before that you are in our hearts to die together and to live together.
