Section 128. The Well Disposed Should Be Exhorted To Thanksgiving And Perseverance — If the sinner is found to be thus disposed, he is to be admonished and earnestly exhorted to pour out his heart in gratitude to God for so great and so singular a blessing, and to supplicate unceasingly the aid of divine grace, shielded by which he may securely combat his evil propensities.
