Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man is powerful and effective.

Hebrews 4:12
For the word of God is living and active. Sharper than any doubleedged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
