'Heartfelt' in the Bible

Heartfelt thanks be to the God and Father of our Lord Jesus Christ--the Father who is full of compassion and the God who gives all comfort.

Receive him therefore with heartfelt Christian joy, and hold in honour men like him;

Therefore confess your sins to one another, and pray for one another, so that you may be cured. The heartfelt supplication of a righteous man exerts a mighty influence.
