That which was from the beginning, that which we have heard, that which we have seen with our eyes, that which we saw, and our hands touched, concerning the Word of life
John writes in the Hebraic style of balancing two lines. The second line is usually in opposition or contrast to the first. (CF. 1 John 1:5, 1 John 2:4, 1 John 2:27). Also in antithesis-- 1 John 3:7-10, 1 John 4:4-6, 1 John 5:18-19.
