'Pure Heart' in the Bible

The one who has innocent hands and a pure heart; the person who does not delight in what is false and does not swear an oath deceitfully.

God, create a pure heart in me, and renew a right attitude within me.

The goal of this instruction is love that flows from a pure heart, from a clear conscience, and from a sincere faith.

Flee from youthful passions. Instead, pursue righteousness, faithfulness, love, and peace together with those who call on the Lord with a pure heart.

Now that you have obeyed the truth and have purified your souls to love your brothers sincerely, you must love one another intensely and with a pure heart.
