1 John 4:17

Herein; according to some, this word refers backward to the preceding verse. The meaning will then be, that by our dwelling in love, and thus in God and he in us, our love is made perfect; and the words following, "that we may have boldness," etc., will express the end towards which that love is directed. According to others, the reference is forward, precisely as in John 15:8, "Herein is my Father glorified, that ye bear much fruit." The meaning will then be, that the perfection of our love consists in its giving us boldness in the day of judgment; and consequently now, in anticipation of that day.

Because; the ground of this boldness.

As he is; as Christ is, in respect to love. He does not say, as Christ was, because Christ's love is not changed by his removal to heaven.

So are we in this world; we manifest in the world the same love which Christ manifested on earth, and now has in heaven.
