Jesus answered and said unto them,
This is the work of God, that you believe on him whom he has sent.

AD 1637
Jesus answered, &c. Believe, i.e, in Myself, Who by so many arguments and miracles have proved that I am the Messiah sent by God. For the sake of modesty He speaks in the third person. As though He said, "That work by which ye will obtain Food from God to nourish the soul unto everlasting life, is to believe in Me. For I bestow this Food upon those who believe in Me. For I Myself am this Food." This He says (verse35).
That ye may believe, and believing, may obey Me, and observe My law and doctrine, and fulfil it indeed. Under the term faith, as a root, Christ and Paul understand all the works of charity, penance, temperance, and all other virtues which faith-stirs up and generates. Wherefore Theophylact says, "Faith assuredly is a holy and perfect work, and satisfies those who possess it. For diligent faith leads to every good work, and good works preserve faith. For works are dead without faith, and faith is dead without works."
