The term ‘mouth’ refers to the exploration of sacred scripture, ‘heart’ embodies the fervor of the spirit, and ‘hands’ represent the diligent execution of divine precepts. This affirmation is echoed by the Apostle Paul, who states: ‘If thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart, that God hath raised Him from the dead, thou shalt be saved: for with the heart thou believest in the truth, and with the mouth shalt confess unto salvation’ (Romans 10:9-10).
