As unpacked in the previous posts, the vow summarizes the Reformed understanding of sinners/saints and their repentance before God. The following prayer of John Calvin seems to be, as it were, an expanded two-part template for the entire third vow:
The Vow (3)
Do you confess that because of your sinfulness you abhor and humble yourself before God, that you repent of your sin, and that you trust for salvation not in yourself...
John Calvin: "Grant, Almighty God, that since we are too secure and torpid in our sins, thy dread majesty may come to our minds, to humble us, and to remove our fear, that we may learn anxiously to seek reconciliation through Christ, and so abhor ourselves for our sins, that thou mayest then be prepared to receive us: and that unbelief may not shut the door against us, enable us to regard thee to be such as thou hast revealed thyself, and to acknowledge that thou art not like us...... but in Jesus Christ alone?
Calvin continues: "... but the fountain of all mercy, that we may thus be led to entertain a firm hope of salvation, and that, relying on the Mediator, thy only-begotten Son, we may know him as the throne of grace, full of compassion and mercy. O grant, that we may thus come to thee, that through him we may certainly know that thou art our Father, so that the covenant thou hast made with us may never fail through our fault, even this, that we are thy people, because thou hast once adopted us in thy only-begotten Son, our Lord Jesus Christ. Amen."**Prayer of John Calvin from his commentary on Hosea
