5:7 What Bengelius has advanced, both concerning the transposition of these two verse s, and the authority of the controverted verse , partly in his Gnomon, and partly in his Apparatus Criticus, will abundantly satisfy any impartial person. For there are three that testify - Literally, testifying, or bearing witness. The participle is put for the noun witnesses, to intimate that the act of testifying, and the effect of it, are continually present. Properly, persons only can testify; and that three are described testifying on earth, as if they were persons, is elegantly subservient to the three persons testifying in heaven. The Spirit - In the word, confirmed by miracles. The water - Of baptism, wherein we are dedicated to the Son, (with the Father and Spirit,) typifying his spotless purity, and the inward purifying of our nature. And the blood - Represented in the Lord's supper, and applied to the consciences of believer. And these three harmoniously agree in one - In bearing the same testimony, - that Jesus Christ is the divine, the complete, the only Saviour of the world.

Alive or Dead --Which?
We have in the text mention made of certain men who are living, and of others who are dead; and, as the two are put together in the text, we shall close by some observations upon the conduct of those who have life towards those who are destitute of it. I. First, then, CONCERNING THE LIVING. Our text testifies that "He that hath the Son hath life." Of course, by "life" here is meant not mere existence, or natural life; for we all have that whether we have the Son of God or no--in the image of the …

Faith and Regeneration
It may not be easy to keep these two things in there proper position, but we must aim at it if we would be wise builders. John did so in his teaching. If you turn to the third chapter of his gospel it is very significant that while he records at length our Saviour's exposition of the new birth to Nicodemus, yet in that very same chapter he gives us what is perhaps the plainest piece of gospel in all the Scriptures: "And as Moses lifted up the serpent in the wilderness, even so must the Son of man …
