The Comforter gives a sweet and plentiful evidence and persuasion of the love of God to us, such as the soul is taken, delighted, satiated with. This is his work, and he does it effectually. To give a poor sinful soul a comfortable persuasion, affecting it throughout, in all its faculties and affections, that God in Jesus Christ loves him, delights in him, is well pleased with him, has thoughts of tenderness and kindness towards him; to give, I say, a soul an overflowing sense of this, is an inexpressible mercy.
This we have in a peculiar manner by the Holy Ghost; it is his peculiar work.
