Barnes' Notes
He that hath ... - This intimate union is further manifested by these facts:
1.That true love to Jesus will produce obedience. See John 14:15.
2.That those who love him will be loved of the Father, showing that there is a union between the Father and the Son.
3.That Jesus also will love them, evincing still the same union. Religion is love. The love of one holy being or object is the love of all. The kingdom of God is one. His people, though called by different names, are one. They are united to each other and to God, and the bond which unites the whole kingdom in one is love.
Will manifest myself to him - To manifest is to show, to make appear, to place before the eyes so that an object may be seen. This means that Jesus would so show himself to his followers that they should see and know that he was their Saviour. In what way this is done, see John 14:23.
