In Thomas Watson’s ‘The 10 Commandments, he writes:
(1) True faith is grounded upon knowledge. Knowledge carries the torch before faith. There is a knowledge of Christ’s orient excellencies. Phil 3:8. He is made up of all love and beauty. True faith is a judicious intelligent grace, it knows whom it believes, and why it believes. Faith is seated as well in the understanding, as in the will. It has an eye to see Christ, as well as a wing to fly to him. Such therefore as are veiled in ignorance, or have only an implicit faith to believe as the church believes—have no true and genuine faith.
